PURPOSE:To secure the sure operation due to the conduction of the first and the second contact points without increasing the dimension of the whole device. CONSTITUTION:The first contact point 23 is fixed on an output member 22, and the second contact point 24 is fixed on a case side 33, and the first contact point 23 is shifted, together with the turn of the output member 22, around the turning center of the output member 22, and the first and the second ccntact points 23 and 24 are brought into slide contact in a prescribed range, and the first and the second contact points 23 and 24 are put into conduction state together.
