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 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.

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: An impact tool includes a tool body, a tool holder, a cylindrical member, a reciprocating member, a motor, a first rotary body, a second rotary body, a swinging member, and clutch mechanisms. The clutch mechanisms are disposed between the first rotary body and the second rotary body on a power transmission path from the motor to the swinging member. The tool holder and the cylindrical member move together as a movable unit with respect to the tool body between a front end position and a separate position, according to a pressing force applied to the tool holder. The clutch mechanisms are each configured to start transmission of the first rotary body to the second rotary body while the movable unit moves from the front end position to the separate position and to interrupt transmission while the movable unit moves from the separate position to the front end position.

Abstract: An effective technique for increasing performance of an auxiliary handle which is attached to a power tool is provided. The auxiliary handle has a grip part, a grip holding part, a mounting part and a support part. The grip holding part is disposed between the grip part and the support part in a longitudinal direction of the auxiliary handle. When the auxiliary handle is attached to a power tool body, the grip part and the grip holding part are held so as to be movable with respect to the mounting part with the support part as a fulcrum.

Abstract: A power tool comprises a motor, a final output shaft, a tool body, a detection device, and a braking device. The motor has a motor body including a stator and a rotor, and a motor shaft extending from the rotor and being rotatable around a first rotational axis. The final output shaft is configured to be rotationally driven around a second rotational axis by torque transmitted from the motor shaft. The tool body houses the motor and the final output shaft. The detection device is configured to detect a locking state of the final output shaft. The braking device is configured to directly act on the motor shaft to brake the motor shaft in response to detection of the locking state.

Abstract: A hammer drill includes a housing inside which a motor, a tubular tool holder, a driving mechanism, a rotation conversion member, and an inner housing are disposed. The driving mechanism is configured to perform at least one of rotation actuation of the tool holder and hammering actuation of a bit. The inner housing supports the driving mechanism, supports the tool holder via a first bearing, and supports an output shaft via a second bearing. The inner housing is divided into a front housing holding the first bearing and a rear housing that is formed in a separate body from the front housing and holds the second bearing. The inner housing is formed by connecting the front housing to the rear housing in an axis line direction of the tool holder. A seal member sealing outside space of the inner housing inside the housing is disposed in the front housing.
