Force-receiving plate for friction device

摘要

A pressure-receiving plate for a friction device includes an annular portion and pawls formed integrally on the inner or outer periphery of the annular portion. The annular portion has one side provided with a friction surface which contacts a friction disk engaged with one of a driving member and a driven member, and another side provided with reduced-thickness portions formed by applying crushing work that takes hardness and surface roughness of the friction surface into consideration. The pawls are engaged with the other of the driving member and driven member.
