Abstract
A brake device includes a padhaving a friction surfaceand a diskhaving a friction surfacesliding on the friction surface. The friction surfaceincludes hard particlesthat are elastically supported in a y direction perpendicular to the friction surface. The friction surfaceincludes a plurality of convex portionsthat is disposed in a direction where the friction surfaceslides on the friction surface. When the friction surfaceslides on the friction surface, the hard particlescontinuously come into contact with the convex portions, respectively, while being displaced in the y direction perpendicular to the friction surface. Accordingly, the brake device can improve abrasion resistance as compared to a brake device that mainly performs abrasive friction. When the hard particlecomes into contact with the next convex portionafter coming into contact with one convex portion, the hard particlecomes into contact with the convex portionat a position lower than the apex of the convex portion. Accordingly, the hard particlescontinuously come into contact with the convex portionsso as to follow the convex portions, respectively. Therefore, it may be possible to obtain a larger frictional force.
