Abstract:
A bearing for a clutch, a clutch operation mechanism, and a clutch. The bearing (11) comprises an inner ring (110), an outer ring, and a rolling body provided between the inner ring and the outer ring, wherein the inner ring (110) comprises: an annular abutting part (111), the annular abutting part radially extending from the inner ring (110), and an annular end surface (1110) of the annular abutting part (111) being used for abutting against a first end surface of a preloaded spring (12), wherein the preloaded spring (12) is used for applying an axial force to the bearing (11); and a protrusion part (112), the protrusion part axially extending from the inner ring (110), so that when the preloaded spring (12) abuts against the annular end surface (1110) of the annular abutting part (111), the tail end at the first end surface of the preloaded spring (12) abuts against the protrusion part (112) to prevent relative rotation between the preloaded spring (12) and the inner ring (110). The clutch has the characteristics of being small in the number of components and easy to mount.
