An apparatus for holding a spring of a clutch has a guide plate which is disposed in an annular recessed portion on a rear side of a clutch plate. A coil spring circumferentially extends in contact with the guide plate. A retainer has a pair of end surface holding portions to contact both ends of the coil spring and a peripheral holding portion to contact a periphery of the coil spring. The guide plate and the retainer are mounted on the clutch plate. A connecting piece is continuously provided on each circumferential end of the guide plate such that the connecting pieces are fit onto the end surface holding portions of the retainer.
