<p>PURPOSE: To set manufacturing tolerances of a window guide or a track easily by forming track receiving head portions which are constituted of two identical plastic half members, energized and held apart from each other in jointing the half members and in sliding-engagement condition with a channel shaped track. CONSTITUTION: When half members 80a, 80b are snap fittingly connected together through a cooperate means 96, bowed leafs 94 engage with each other, primary and secondary hinges 90, 92 rotate them against their self-biased force, and a neck part 88 and a head part 86 are moved so as to be apart from each other. As a result, the head part 86 are placed so that their free edges may face each other in the opposite direction, and the primary and secondary hinges 90, 92 can rotate against the self-biased force when the head part 86 is put in a guide track 52 or 54. The self-biased force makes the head part 86 locate so as to engage with the guide track 52 or 54 when connected therewith, thereby preventing rattling noise therebetween.</p> |
