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 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.

Abstract: A rational technique which can realize vibration suppression and reduction of unstable driving elements of a striker. A representative power tool, a first compensation mechanism moves a swinging mechanism from a swinging mechanism reference position to a swinging mechanism moving position and moves a cylinder to a second side, thereby increasing the volume of an air chamber. Further, the second compensation mechanism moves an intermediate element from an intermediate reference position to an intermediate element moving position and moves a striking element to the second side, thereby compensating the volume of the air chamber.

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.
