  • Patent number: 11460088
    Abstract: A damper includes: first and second rotating elements rotatable around a rotation center; an elastic element elastically expanding and contracting in response to relative rotation of the first and second rotating elements; and a limiter provided in the first rotating element. The limiter includes a lining plate having a first sliding surface, a first cover plate having a second sliding surface and a first abutting surface, a second cover plate having an outer edge part and an inner edge part, and a biasing member. When a difference in torque between the lining plate and the first cover plate is a predetermined value or more, the first sliding surface slides with the second sliding surface, and the second sliding surface is inclined with respect to the first abutting surface so as to face the second direction as going radially inward in a free state of the first cover plate.
