Abstract:
To provide a technique contributing to easy detachment of a front end tool, in a working tool in which the front end tool is driven in an oscillated manner.SOLUTION: A vibration tool comprises an inner housing 3, a spindle 5, a clamp shaft 61, a clamp spring 65, a clamp member 71, a collar 75, a lever 77 and a push-down sleeve 671. The collar 75 holds the clamp member 71 vertically movably between a lock position at which the member is engaged with the clamp shaft 61 while the member cannot radially move and an unlock position at which the member can radially move. The lever 77 moves the clamp member 71 downward with respect to the collar 75 and the spindle 5, in accordance with predetermined releasing operation. The clamp member 71 moves from the lock position to the unlock position with respect to the collar 75, in conjunction with the releasing operation. The clamp member 71 pushes a front end tool 91 downward through the push-down sleeve 671, in a course of moving downward.SELECTED DRAWING: Figure 7
