Abstract
A first friction member supporting member is provided on an inner circumference of a clutch retainer and a second friction member supporting member is provided on an outer circumference of a hub. A piston is disposed within the clutch retainer and is moved by hydraulic pressure to thereby generate friction. A plurality of circumference protrusions having different inner diameters in a radial direction are formed respectively on the first and second friction member supporting members. The circumference protrusion of the second friction member supporting member is disposed to overlap with an inner circumference portion of the circumference protrusion of the first friction member supporting member. Surfaces of the circumference protrusions of the first and second friction member supporting members facing with each other are formed as corresponding slanted surfaces and friction members are disposed on the slanted surfaces of the circumference protrusions.
