Abstract:
In order to solve the problems with a prior art E type snap ring that the snap ring snaps away easily and fixing&sol removing work thereof is difficult, a plurality of inner notches (3, 3a, ...) and protrusions (4, 4a, ...) are formed alternately at the inner circumferential part of a C−shaped basic material provided with an opening (1) at one position of the outer circumferential part thereof, and outer notches (5, 5a, ...) are formed at the positions of the outer circumferential part corresponding to the parts between the inner notches (3, 3a, ...), wherein the opening (1) is enlarged toward the outer circumferential side. Since the snap ring is resiliently deformed easily without requiring a more than necessary force at the time of fixing&sol removing, the snap ring for shaft can be fixed&sol removed easily while preventing it from snapping away especially at the time of fixing.
