    Abstract: A work tool includes a spindle, a clamp shaft, a holding member, an engagement member and a first biasing member. The holding member has a pass-through part. The engagement member is rotatable around a driving axis relative to the holding member between a first position in which the engagement member is allowed to pass through the pass-through part and a second position in which the engagement member is engaged with the holding member. The engagement member allows the clamp shaft to move in an up-down direction relative to the holding member when located in the first position, and to prevent the clamp shaft from moving downward relative to the holding member when located in the second position. The holding member is configured to fixedly hold the clamp shaft relative to the spindle while being biased upward by the first biasing member, with the engagement member in the second position.

    Abstract: A power tool includes a tool body, a motor, a handle part, and an elastic member. The tool body extends along the driving axis in the front-rear direction. The motor has a motor shaft. The motor shaft is rotatably supported by the tool body and extends in the front-rear direction. The handle part includes a grip part. The grip part extends in a direction crossing the driving axis. The elastic member is interposed between a rear end portion of the motor shaft and an inner wall surface of the handle part. The elastic member biases the motor shaft and the handle part away from each other in the front-rear direction.

    Abstract: A power tool includes a drilling tool and a dust collector configured to be removably attached to the drilling tool. The dust collector includes a dust collector body, a passage part provided in the dust collector body and having elasticity, and a storing part configured to be removably attached to the dust collector body and to store dust. The passage part includes a drilling tool mounting port part configured to be connected to the drilling tool while pressing a specified region of the drilling tool, and a storing part mounting port part configured to be connected to the storing part while pressing a specified region of the storing part. Air containing the dust is led through the dust collector body to the storing part, and the air from which the dust has been separated in the storing part is led through the passage part into the drilling tool.

    Abstract: A power tool includes a motor, a driving mechanism, a body housing, a handle, and a rear position defining member. The driving mechanism is driven by the motor and configured to drive a tool bit in a longitudinal direction. The body housing houses the motor and the driving mechanism. The handle is connected to the body housing so as to be allowed to move with respect to the body housing between a front position and a rear position in the longitudinal direction, while being biased by a biasing member in the longitudinal direction. The handle includes a handle base and a handle cover. The rear position defining member extends from the body housing to a position between the handle base and the handle cover in the longitudinal direction and is configured to define a rear position of the handle.

    Abstract: An electrical hammer (100) comprises a main housing (101), a hand grip (500) connected to the main housing (101) via a compression coil spring (321). In the electrical hammer (100), a hammer bit (119) is driven by a first motion converting mechanism (120) and thereby a hammering operation is performed. During the hammering operation, the hand grip (500) is moved against the main housing (101) in a state that biasing force of the compression coil spring (321) is applied on the hand grip (500). Further, the electrical hammer (100) comprises a second motion converting mechanism (220) which drives a counterweight (231).
