ABSTRACT:
A chain comprising links and pins formed from fiber reinforced thermoplastic resin is disclosed. Each link has bores, and each pin has a body for insertion through the bores of adjoining links to connect the links pivotally. The body has two diametrically opposite rows of grooves formed in its peripheral surface, has a front end from which an annular shell projects coaxially and an axial protrusion extends through the shell coaxially, and has a rear end formed with a flange. The shell has a radially outwardly projecting shoulder formed around its mid-portion, has a frustoconical front end portion, and has radially extending slits which makes the shell radially compressible. The link which has a bore positioned at the inlet for the insertion of the pin, has bosses which are engageable with the flange for holding the pin against rotation to maintain the rows of grooves at right angles with respect to a longitudinal direction of the links. The grooves are continuous between two P and Q planes along which shearing forces act upon the pin.
