The present invention is for enlarging the moving stroke of a movable member according to rotation of a lever. Operation projecting portions for moving a contact holder are provided in a moderation piece provided in the base end portion of the lever, movably in the axial direction. When the lever is rotated in the arrow A direction, the moderation piece moves in the arrow B direction while sliding a cam surface. According thereto, the operation projecting portions press the inclined surface of guiding portions so as to move the contact holder in the arrow C direction. At the time, since the moving amount of the moderation piece in the axial direction can be added to the moving stroke L2 of the contact holder, the moving stroke L2 of the contact holder can be enlarged compared with the case with the operation projecting portions provided in the lever.
