An accommodating portion (13) is formed at the center of a body (8) of a first member (1) having a belt attachment (10). The accommodating portion (13) has an opening (14) on the front and back sides thereof, the opening (14) being sufficient for molding a bulging head (42) of the rotary shaft (40) therein, a groove (15) sufficient for molding a neck portion (41) of the rotary shaft (40) is provided at the center of the lower side of the opening, and a concave groove (22) capable of molding a part of the neck portion (41) is formed in lateral direction. The rotary shaft (40) is integrated with the second member (2) at an upper side of a body (9) thereof and has an insert hole of an insert-type male body at a lower side. Since a gap is generated between the first member and the second member during the molding process and movement thereof becomes shaky, a retainer (34) having a bearing (35) at a distal end thereof is fitted between the bulging head (42) of the rotary shaft and the lower side (23) of the accommodating portion (13) to prevent shaky movement. <IMAGE> |
