Abstract
A number of link plates molded of synthetic resin are pivotally connected together by connecting pins to form a molded conveyor particularly suitable for the conveyance of delicate or easy-to-break articles. Each link plate has a plurality of aligned bush holes formed at intervals along a trailing end edge of the link plate, and a plurality of aligned pin holes formed at intervals along a leading end edge of the link plate. Each of the connecting pins is inserted alternately into the pin holes in one link plate and the bush holes in the adjacent link plate to pivotally connect these two link plates. A locking projection formed on the connecting pin to lock the connecting pin in position against detachment is located closer to one end of said connecting pin than to a longitudinal central portion of said connecting pin. The locking projection thus arranged reduces a stroke of hammering required to drive the connecting pin into the pin and bush holes. The connecting pin further has a flange-like stopper serving to position the locking projection within one of the bush holes when the connecting pin is in its fully inserted position.
