Abstract: A reciprocating tool includes a motor, a driving mechanism, a body housing, a movable part, and a vibration control mechanism. The driving mechanism includes a reciprocating member configured to reciprocate in a first direction. The movable part is connected to the body housing via a first elastic member and a second elastic member to be relatively movable in the first direction. The vibration control mechanism includes at least one weight configured to move in a direction opposite to the reciprocating member. The center of gravity of the at least one weight is offset from the driving axis in a second direction. In the second direction, the first elastic member is closer to the center of gravity than the second elastic member. A load of the first elastic member when the movable part is placed in a closer position is smaller than a load of the second elastic member.

Abstract: A dust collecting device 140 is provided which is attached to an electric hammer 101 having a side handle 110 which is removably attached to a body 103. The dust collecting device 140 has a dust collecting hood 141 and a hose holder 145. The side handle 110 has a mounting ring 111 which is mounted on the body 103, a grip 121 and a grip securing part 131. The grip 121 is secured by moving relative to the grip securing part 131 in a direction crossing an axial direction of the hammer bit 200. By this relative movement for securing the grip 121, the hose holder 145 is held between the grip 121 and the grip securing part 131.

Abstract: A motor unit may include: a motor including a motor shaft extending in a first direction; a body housing disposed on an outer side of the control circuit board and the motor housing; a first fixing part configured to be fixed to the working unit; a first and second vibration-proof members disposed between the body housing and the motor housing. The first fixing part is placed on a placement surface when the motor unit is placed on the placement surface. In an up-down direction perpendicular to the placement surface, at least a part of the first vibration-proof member and at least a part of the second vibration-proof member may be disposed below an upper end of the motor when the motor unit is placed on the placement surface. When the motor unit is viewed along the first direction, the motor may be disposed between the first second vibration-proof members.

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 rotary hammer includes a motor, a manipulation member, a main switch, a mode-switching member, a first locking member and a second locking member. The first locking member is configured to selectively lock the manipulation member in an OFF position according to a switching position of the mode-switching member. The second locking member is configured to selectively lock the manipulation member in an ON position according to the switching position of the mode-switching member. The first locking member is allowed to lock the manipulation member in the OFF position both when a hammer mode has been selected and when a drill mode has been selected. The motor is allowed to be driven in a state in which the manipulation member is locked in the ON position by the second locking member only when the hammer mode has been selected.

Abstract: A rotary tool includes a motor, a final output shaft, a housing, a detecting mechanism, an interrupting mechanism and a solenoid. The motor includes a motor body and a motor shaft. The final output shaft is configured to be rotationally driven by torque transmitted from the motor shaft. The housing houses the motor and the final output shaft. The detecting mechanism is configured to detect a motion state of the housing. The interrupting mechanism is provided on a transmission path of the torque from the motor shaft to the final output shaft, and configured to interrupt transmission of the torque. The solenoid includes a linearly movable actuation part and is configured to mechanically actuate the interrupting mechanism via the actuation part based on the motion state of the housing detected by the detecting mechanism.
