Abstract:
[Problem] To provide a technique in which the tip tool of a work tool can be held using a simple action. [Solution] There is configured an electric vibration tool (1) provided with a spindle (120) and a clamp shaft (123), the electric vibration tool (1) driving a blade (10) sandwiched by an outer flange (122) and a clamp head (124). The electric vibration tool (1) has: a ball (135) for holding the clamp shaft (123) against the spindle (120) in a fixed manner; a ball-holding member (131) for moving the ball (135); and a first coil spring (137) for urging the ball-holding member (131). The ball (135) is configured so as to be capable of moving between a first position at which the clamp shaft (123) can be held and a second position at which the clamp shaft (123) cannot be held. The ball-holding member (131) is configured so as to move the ball (135) from the first position to the second position. The first coil spring (137) is configured so as to urge the ball-holding member (131) and restrict movement of the ball-holding member (131) when the ball (135) is at the second position.
