Abstract
A work tool includes a motor, a tool-mounting part, a rotary shaft, a rotating member, a switch, an operation member and a lock mechanism. The rotating member is held rotatably around a rotation axis of the rotary shaft and configured to transmit torque to and from the rotary shaft while being allowed to rotate relative to the rotary shaft. The rotating member is configured to rotate together with the rotary shaft by action of transmitting the torque when the operation member is moved from the OFF position to the ON position and the lock mechanism allows the rotating member to rotate, and configured to apply a braking force to the rotary shaft by action of transmitting the torque when the operation member is moved from the ON position to the OFF position and the lock mechanism non-rotatably locks the rotating member.
