PROBLEM TO BE SOLVED: To accurately keep a travel amount of a support member at a desired value in a wear compensation mechanism compensating the wear of a friction member by moving the support member on a clutch cover side. SOLUTION: The wear compensation mechanism 18 has a first inclined face provided on a friction member side of a clutch cover 15 and extending in the direction of rotation, an adjust ring 59 having a second inclined face arranged in the cover 15 so as to rotate relatively and move in the axial direction and in contact with the first inclined face so as to compensate mutually on the clutch cover side, an adjust spring 61 energizing the ring 59 for the cover 15 in the direction of rotation so that the ring 59 leaves the cover 15 in the axial direction, and a detection mechanism 56 for detecting a wear amount of a friction member. The detection mechanism 56 comes into contact with a friction member side of the ring 59 to prevent the travel of the ring 59 onto the friction member side and allows the travel of the ring 59 when the friction member is worn.
