To provide a clutch mechanism which can surely transmit power and suppress a jump small by a relatively small pressing force and to provide a clock equipped therewith.
A clutch mechanism of a clock comprises a drive side clutch member 50 which has a drive side planar surface part 52 and many drive side engaging projection parts 53 formed in the drive side planar surface part 42 at intervals and a driven side clutch member 40 which has a driven side planar surface part 42 and many driven side engaging projection parts 43 formed in the driven side planar surface part 42 at intervals. The drive side engaging projection parts 53 and driven side engaging projection parts 43 are respectively tapered so as to make a cross-sectional area smaller toward the tip side. The drive side clutch member 50 and driven side clutch member 40 approach and separate from each other so as to allow at least a part of the drive side engaging projection parts 53 to be engaged with and disengaged from at least a part of the driven side engaging projection parts 43.
