PROBLEM TO BE SOLVED: To provide a technique capable of holding a tip tool by a simple action in a work tool.SOLUTION: An electric vibration tool includes a ball 135 for holding a clamp shaft 123 against a 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 to be capable of moving between a first position where the clamp shaft 123 can be held and a second position where the clamp shaft 123 cannot be held. The ball-holding member 131 is configured to move the ball 135 from the first position to the second position. The first coil spring 137 is configured to urge the ball-holding member 131 and restrict the movement of the ball-holding member 131 when the ball 135 is at the second position. |
