    摘要： To reduce size increase, a power tool includes a motor, an output shaft located frontward from the motor, rotatable by the motor, and having an insertion hole extending rearward from a front end of the output shaft, a bearing supporting the output shaft in a rotatable manner, a locking member supported by the output shaft and movable to a locking position for locking a tip tool placed in the insertion hole and to an unlocking position for unlocking the tip tool, a bit sleeve surrounding the output shaft, and movable to a movement-restricting position for restricting radially outward movement of the locking member and to a movement-permitting position for permitting radially outward movement of the locking member, and an operable member operable to move the bit sleeve and at least partly overlapping the bearing in an axial direction.
