Moreover, a projection piece 20 pushes up the lower side ridge of a stopper 18 as the lock piece 14 turns and the stopper 18 is turned upward in interlocking with the lock piece 14 against an elastic arm 19. Then the holder 4 is in the over-stroke state. When the holder 4 is detached, the holder 4 is restored to the forward direction by a spring 7 and the lock pin 10 is engaged with an engaging section 14a of a lock piece 14 and the stopper 18 engages therewith from the back side to clip the lock pin 10. Thus, no play exists, modulation noise is reduced and its sound quantity is improved.
