Claim:
A damper mechanism, comprising: a first rotary body; a second rotary body being arranged such to be rotatable with respect to the first rotary body, the second rotary body including an annular main body section, and a plate-like transmitting section having a first protruding section extending outward in a radial direction from the main body section, and a second protruding section extending in the radial direction, the second protruding section having a width which extends toward a first side in an axial direction from a circumferential-direction-facing edge portion being an end part of the first protruding section, the second protruding section forming an angle being substantially perpendicular with the first protruding section, the first protruding section including a first protruding section main body that is arranged in substantially the same position as the main body section in the axial direction and extends outward in the radial direction from the main body section, and an outside section that extends in the radial direction, and has a width extending in the rotational direction from a rotational-direction-facing edge portion of the first protruding section main body and bulges out farther in the axial direction than the first protruding section main body; a spring elastically connecting the first rotary body and the second rotary body together in a rotational direction and being configured to be compressed between the first rotary body and the transmitting section of the power transmitting part; and a spring seat arranged between the first rotary body and the transmitting section and supporting an end portion of the spring.
