<p>A braking device is provided with a pad (100a) having hard particles (102) on a wavelike friction surface (101), and a disc (200a) having a hard layer (203) on a wavelike friction surface (201) which slides on the wavelike friction surface (101). The wavelike friction surface (201) is permitted to be a groove section in a direction wherein the wavelike friction surfaces (101, 201) slide on each other, and the wavelike friction surface (101) is permitted to be a protruding section which abuts to the groove. Thus, an actual contact area of the friction surfaces having the hard members is increased, and a higher frictional force can be obtained without sacrificing abrasion resistance.</p> |
