A torque fluctuation absorbing device includes a damping mechanism connected with an input shaft of a transmission. The damping mechanism has an approximately annular-shaped frictional member, which is fixed to both surfaces of a disc disposed at outer peripheral portion. The torque fluctuation absorbing device further includes a flywheel for transmitting driving force from a driving power source, a first plate rotated with the flywheel and abutting on a first surface of the frictional member, a second plate abutting on a second surface of the frictional member, a coned disk spring for biasing the second plate against the frictional member, a supporting member rotated with the first plate and supporting the coned disk spring, and a plurality of fixation members for fixing the first plate with the supporting member. The first plate includes a reinforcement portion which reinforces rigidity of the first plate at an inner circumference portion located radially inwardly relative to the frictional member.
