Abstract
A dust boot for a constant velocity universal joint has a bellows-shaped boot made of chloroprene-rubber substantially excluding wax and a polyamide resin coating layer having excellent wear resistance, which is formed on the outer surface of the bellows-shaped boot without peeling. Between the coating layer and the polyamide resin boot is formed a primer layer made of a mixture of chloroprene-rubber and isocyanate compound so that the coating layer does not peel off from the bellow-shaped boot.
