Abstract: An impact driver or impact tool includes a motor, a motor housing that houses the motor, a grip housing integrally provided with the motor housing, a hammer case is disposed frontward of the motor housing, a spindle rotated by the motor, a hammer housed inside the hammer case and configured to be rotated by the spindle, and an anvil housed inside the hammer case which anvil is configured to be impacted by the hammer. In this impact driver, a length from a rear end of the motor housing to a front end of the anvil (i.e., the front-rear length of a main body) is less than 128 mm.

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: 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: An electric caulking gun may include a main body portion including a cartridge setting portion to which a cartridge containing a caulking material can be set, an electric motor disposed within the main body portion, and a push rod configured to be pressed against the cartridge for dispensing the caulking material from the cartridge. The push rod may be coupled to the electric motor so as to advance and retract along a moving path. The electric motor may extend in a right and left direction across a vertical plane including the moving path of the push rod.

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.
