One of the eye and hook members has an integral bearing portion divided into a pair of opposed bearing halves by a space, the two bearing halves having a pair of aligned through-holes communicating with the space. The other member has an integral arm portion extending into the space and terminating in an enlarged end which is loosely received in the through-holes in the bearing halves across the space for rocking movements. In production, the eye and hook members are molded simultaneously molded in only one step of molding operation in coupled state. |
