Abstract

A motorcycle rear swing arm structure includes a chain case having partition members for obstructing the course of granular particles against the surface of the brake disc on the wheel carried by the swing arm. The chain case can also be provided with baffle members effective to collect droplets of oil sprayed from the drive chain sprocket and for conducting it for discharge away from the swing arm.
