Abstract
A platefastened to a D-cut sectionof a rotation shaftby caulking has an engaging holeprovided therethrough. Further, a positioning protrusionfor engaging the engaging holeis provided in a leaf springsandwiched between the rotation shaftand the plate. The inclination θof the leaf springmade by the amount of a clearance B between the engaging holeand the positioning protrusionthat are distant from the rotation central axis X is smaller than the inclination θmade by the amount of a clearance A between the D-cut sectionand the straight portionthat are close to the rotation central axis X. Thus, the backlash in the rotation direction of the leaf springcan be reduced by providing the positioning protrusionand the engaging hole
