Abstract: An electric power tool in one aspect of the present disclosure comprises a motor, a hitting mechanism, a hitting detector, and a control unit. The control unit is configured to set a control amount of the motor so that the motor rotates at a lower speed than a speed in the target rotation state during an initial driving period, and switch the control amount to a final control amount corresponding to the target rotation state when the initial driving period elapses. The initial driving period is a period from when generation of a hitting force is detected by the hitting detector until a predetermined first time period elapses, after the motor is started driven.

The anvil shaft includes a first shaft having a circular cross section, a second shaft having a rectangular cross section, and an intermediate portion between the first and second shafts. The second shaft includes four flat portions and four flat portion connectors. Each flat portion has a first edge and a second edge. The intermediate portion includes support portions each connected to the first edge and is connected to the second edge of each flat portion at positions rearward from the support portions.

Abstract: A power tool includes an anvil (14) operably driven by a motor (10); an insertion hole (91) defined the anvil, into which a bit is insertable; a through hole (92) extending radially from the insertion hole; a ball (93) disposed in the through hole; and a manually-movable sleeve (99) mounted around on the anvil and being axially slidable relative to the anvil. At a retracted position, the manually-movable sleeve presses the ball radially inwardly. At an advanced position, the manually-movable sleeve releases the pressing of the ball. A flat spring (97) is configured to bias the ball radially inwardly. The manually-movable sleeve has a length such that the flat spring is exposed at the advanced position.
