Abstract:
1. A damper mechanism, comprising: a first rotating member; and a second rotating member arranged to face said first rotating member, having a rotation center axis identical to a rotation center axis of said first rotating member, and being capable of relative displacement at a predetermined angle in a circumferential direction of said rotation center axis, wherein said first rotating member includes a first pressure contact region arranged annularly around said rotation center axis and coming into pressure contact with said second rotating member, said second rotating member includes a second pressure contact region arranged with a predetermined spacing around said rotation center axis and coming into pressure contact with said first pressure contact region, said first pressure contact region has a first friction region and a second friction region larger in friction coefficient than said first friction region, said first friction region and said second friction region being alternately arranged along the circumferential direction, said second pressure contact region is located at a central position of said first friction region in the circumferential direction when there is no fluctuation in torque input to the damper mechanism from outside, and a central portion of said second friction section in the circumferential direction is larger in friction coefficient than a region of said second friction section adjacent to said first friction section.
