Abstract

A clutch device to limit transmission of back torque includes a first rotary member, a second rotary member, a first friction plate, a second friction plate, and a plurality of friction materials. The second rotary member is disposed to be rotatable relative to the first rotary member. The first friction plate is configured to be rotated unitarily with the first rotary member. The second friction plate is configured to be rotated unitarily with the second rotary member. The plurality of friction materials are fixed to the first friction plate. The plurality of friction materials are aligned in a circumferential direction and each includes a planar portion and a slope portion. The planar portion is in contact with the second friction plate. The slope portion slants to face an axial direction and to face a direction that the first friction plate is rotated relative to the second friction plate in deceleration.
