ABSTRACT:
As a disc having teeth on its periphery is turned, one end of an engagement piece is engaged with a first lock member, a first protrusion provided on the engagement piece at that end portion is disengaged from the disc, and a second protrusion of the engagement piece at the other end portion thereof is engaged with one of the teeth of the disc. Each time one of the teeth of the disc crosses over the second protrusion, the latter pivots about the point of its engagement with the first lock member, driving the free end of the second resilient piece into and out of contact with the first contact piece. When the disc is turned in the opposite direction, the other end of the engagement piece is engaged with the second lock member to disengage the second protrusion from the disc and to engage the first protrusion with the periphery of the disc. And each time one of the teeth of the disc crosses over the first protrusion, the latter pivots about the point of its engagement with the second lock member, thereby driving the free end of the first resilient piece into and out of contact with the second contact piece.
