Abstract: A driving tool includes a head-guide surface and a pair of leg-guide grooves, both are formed in a driving passage extending in a driving direction. The head-guide surface slidably guides a head of a U-shaped driving member. Each of the pair of leg-guide grooves is recessed from the head-guide surface toward a side of a first end surface of a tool main body. Legs of the driving member enter the leg-guide grooves. The driving member is driven in an inclined posture in which the legs enter the leg-guide groove, thereby avoiding a slipping off posture in which a driver is deviated from the driving member owing to a reaction force occurred when the driving member is driven by the driver.

Abstract: A rotary shaft is spline coupled to a carrier of a final-stage planetary gear mechanism. A bearing for supporting the rotary shaft is arranged on an outer circumferential side of the carrier. The bearing and the carrier are arranged so as to overlap in a direction perpendicular to a motor axis.

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 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 movable support at least partially supports a final output shaft and a driving mechanism, and is integrally movable relative to a housing in an axial direction of a driving axis. A biasing member biases the movable support toward a front side in the axial direction. A first guide shaft extends in the axial direction and slidably guides the movement of the movable support in the axial direction. At least one intermediate shaft rotates in response to rotation of a motor shaft and transmit power of the motor to the driving mechanism. At least one bearing supports an end portion of the at least one intermediate shaft is located in the front side in the axial direction. A single metal support is immovable relative to the housing and supports the at least one bearing. The single metal support has a first hole for partially receiving the first guide shaft.

Abstract: An impact tool includes a housing; and a motor, a tubular tool holder, a driving mechanism, a rotation shaft, a driving mechanism housing region inside the housing. The tool holder has a distal end on which a bit is mountable. The driving mechanism is configured to hammer the bit. The rotation shaft is disposed in the driving mechanism and rotates by a rotation of an output shaft of the motor. The driving mechanism housing region houses the driving mechanism in a sealed state inside the housing. The air escape path that releases air inside the driving mechanism housing region to outside of the driving mechanism housing region is formed inside the rotation shaft while an inlet of the air escape path is formed on an outer peripheral surface of the rotation shaft.
