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: A power tool includes a tool-main-body part, an electric motor as a drive source, a grip part, which extends downward from the tool-main-body part and is configured to be gripped by a user, and a power-supply unit at a tip of the grip part. The power tool includes a controller configured to control the operation of the electric motor, the controller being located on the power-supply unit, and a display controlled by the controller and configured to indicate an operating state of the electric motor. The controller and the display each have a flat-plate shape and are disposed along a surface direction with respect to one another, and the display includes a first portion that overlies the controller and a second portion that projects beyond an end edge of the controller.

Abstract: An electric power tool may include a three-phase brushless motor configured to drive a tool, a gear reducer provided between the motor and the tool. The gear reducer is configured to selectively change a reduction ratio from the motor to the tool between a first reduction ratio and a second reduction ratio. The electric power tool may further include a motor controller configured to drive the motor with rectangular waves. The motor controller is configured to selectively change a conduction angle of each rectangular wave between at least a first conduction angle and a second conduction angle.
