Abstract: It is an object of the invention to provide a technique for enhancing the operability of a power tool.A representative screwdriver 100 is provided which has a motor 110 and a driving mechanism 120. The driving mechanism 120 has a rotation transmitting mechanism including a driving cam 137 and a driven cam 157, and a cam engagement state is switched by movement of the spindle 150 in a longitudinal direction of the spindle. The position of the spindle 150 in the longitudinal direction is detected by a detecting mechanism 162 that is disposed on the opposite side of the rotation transmitting mechanism from a front end region in the longitudinal direction of the spindle 150. A controller 180 controls the rotation speed of the motor 110 based on the detection result of the detecting mechanism 162 and drives the motor 110.

Abstract: A power tool, such as a hammer driver-drill (1), includes a spindle (26) that is axially and rotatable supported inside a metal gear case (41). A first cam (83) is affixed to the spindle so as to rotate therewith and is housed in the gear case (41). A second cam (84) is disposed around spindle such that it is rotatable separately with respect to the spindle and can be brought into contact with the first cam. Hammer-switching levers (95) are movable relative to the gear case between an advanced position, at which rotation of the second cam is restricted (blocked), and a retracted position, at which the rotational restriction on the second cam is released. Receiving members (89) are respectively interposed between the gear case and the hammer-switching levers and are configured to absorb vibration generated when a hammering operation is being performed using the power tool.

Abstract: An impact tool includes a brushless motor having a rotor extending in a front-rear direction and disposed in a motor housing constituted by left, right and rear motor housings. A battery pack is disposed below the motor housing in an up-down direction. A plurality of first screws extend in a left-right direction and fix the left motor housing to the right motor housing. A plurality of second screws extend in the front-rear direction and fix the rear motor housing to the left and right motor housings. A fan is disposed between the rotor and the rear motor housing, a grip housing is disposed downward of the motor housing, and a planetary gear mechanism is disposed frontward of the motor. A spindle is disposed frontward of the planetary gear mechanism, a hammer is disposed on an outer circumference of the spindle, and an anvil is disposed frontward of the hammer.
