The space between the outer side-surfaces 17 of a pair of side-wall sections 4 is not parallel to each other due to differences in expansion amount during plastical deformation. In use, a load is applied to the pivot 3 from the side where the space between the outer side surfaces 17 is narrow to the side where the space is broad. A crimped section 13a is formed on the outer periphery at the opposite end surfaces of the pivot 3, on the half on the side where the space between the outer side surfaces 17 is narrow. Therefore, the outer peripheral surface of the opposite ends of the pivot 3 comes into contact with the inner peripheral surface of the through hole 11 on the load support side. Consequently, the load is sufficiently supported by the contact surface, and even after being used for a long time of period, lost motion is prevented from occurring on the support section at the opposite ends of the pivot 3 with respect to the pair of side-wall section 4. <IMAGE> |
