Abstract

A roller brake or drum brake for a two-wheeler includes a guide case rotating with a wheel, a ring of a sintered copper alloy that is fixedly fitted into the guide case, and a brake shoe of an iron material that is pressed against the inner peripheral surface of the ring thereby exhibiting a braking effect. The sintered copper alloy forming the ring contains hard particles dispersed in the interior of respective grains of copper alloy powder forming the matrix.
