Abstract: A dust collection cup includes a cylindrical attachment to cause a bit to extend through the attachment, a cylindrical dust collector located in front of the attachment to cause the bit to extend through the dust collector, a seal between the attachment and the dust collector and having a through-hole to receive the bit, and a connection port connectable to a dust collection hose and located on an outer circumferential surface of the attachment outward in a radial direction of the bit from the seal and rearward from the seal. The connection port has a distance in the radial direction of the bit from an axis of the attachment to an outermost position longer than a distance in the radial direction of the bit from the axis to a position on the outer circumferential surface of the attachment that is opposite to the outermost position from the axis.

Abstract: A reciprocating tool includes a body housing, a handle member and an elastic member. A first one of the body housing and the handle member includes a first coupling part, while a second one includes a second coupling part. The first coupling part includes an internal space, and an opening that communicates with the internal space and an outside space of the first coupling part. At least a portion of the second coupling part protrudes into the internal space through the opening and is movable relative to the first coupling part in the front-rear direction within the opening. The elastic member is disposed in the internal space and is configured to bias the first coupling part and the second coupling part such that the body housing and the handle member are biased away from each other in the front-rear direction.

Abstract: A dust collection cup allows a bit tip to be viewable without being detached or replaced. A dust collection cup is attachable to a front cylindrical portion of a hammer drill. The dust collection cup in an attached state allows a bit attached to the front cylindrical portion to extend through the dust collection cup. The dust collection cup includes an attachment attachable to the front cylindrical portion, and a body connectable to the attachment. The body includes an extendable unit including at least a portion in an axial direction retaining a predetermined length.

Abstract: A power tool, such as a hammer drill (100), has first and second battery mount parts (160A, 160B) that are aligned in a longitudinal direction of the power tool. First and second batteries (170A, 170B) are mountable thereon in series along a straight line that extends in the longitudinal direction. The first battery (170A) is mounted on the first battery mount part (160A) by sliding along the straight line towards the second battery mount part (160B). The second battery (170B) is mounted on the second battery mount part (170B) by sliding along the straight line towards the first battery mount part (170A).

Abstract: A power tool includes a tool body, a motor, a handle, at least one biasing member, and at least one guide part. The handle is connected to the tool body to be pivotable and to be movable in at least a front-rear direction relative to the tool body. The handle includes a cover part covering a portion of the tool body and a grip part extending in a cantilever manner from the cover part. The at least one biasing member biases the tool body and the handle away from each other in the front-rear direction. The at least one guide part includes a first portion disposed on a portion of the tool body covered by the cover part, and a second portion disposed on the cover part of the handle and connected to the first portion to be movable in at least the front-rear direction relative to the first portion.

Abstract: A power tool having a hammer mechanism comprises a tool body, a motor, a handle, at least one biasing member, and at least one elastic member. The handle is connected to the tool body to be movable in at least a front-rear direction. The handle includes a cover part covering a portion of the tool body, and a grip part connected to the cover part. The at least one biasing member is disposed between the tool body and the handle and biases the tool body and the handle away from each other in the front-rear direction. The at least one elastic member is disposed between the tool body and the cover part of the handle such that the at least one elastic member is movable relative to the tool body and the handle and is shear-deformable in response to a relative movement of the tool body and the handle.

Abstract: In a dust collector for electric power tool, while a casing includes a tubular suction opening portion disposed to protrude forward, a dust collecting route is formed in the casing to ensure capturing a dust suctioned with an air by a filter disposed in a dust box. The suction opening portion is abutted on a surface to be processed and a tool bit of a hammer drill is passable through the suction opening portion. The dust collecting route suctions the air from the suction opening portion and guides the air into the dust box disposed to the casing. The dust box includes a dust removal device (rubber) configured to directly act to the filter from outside to remove the dust accumulated on the filter.

Abstract: A power tool, such as a rotary hammer, includes a housing, an output shaft for mounting a tool accessary and a motor having a motor shaft that generates a rotational output for rotating and linearly hammering the output shaft. The rotational output of the motor shaft is coupled to the output shaft via a driving mechanism that includes a hammer mechanism. An intervening member is axially movable relative to the motor shaft and is operably coupled between the motor shaft and the hammer mechanism. The hammer mechanism and the output shaft are supported by a movable support that is axially movable relative to the housing. Because the output shaft and the driving mechanism are movable relative to the motor and the housing, which preferably includes handle, via the intervening member and the movable support during hammering operations, vibration generated during hammering operations can be dampened before reaching the housing.

Abstract: A work tool includes a motor, a driving mechanism, a body housing and a handle. The driving mechanism is configured to perform an operation of linearly reciprocating the tool accessory along a driving axis extending in a front-rear direction. The handle includes a grip part extending substantially in an up-down direction, and a battery-mounting part provided on a lower side of the grip part. An upper end portion of the handle is connected to a rear end portion of the body housing via an elastic member so as to be movable relative to the body housing. A lower end portion of the handle is connected to the rear end portion of the body housing so as to be rotatable relative to the body housing, around a rotation axis extending in a left-right direction. The rotation axis is located on a lower side of the battery-mounting part.
