Disclosed is a rotation transmission mechanism capable of realizing a bicycle and the like with better usability than an existing art. The rotation transmission mechanism (1) includes: an internal rotation member (3) inserted by a crankshaft (2) of a bicycle; and an external rotation member (4) configured on the internal rotation member (3) in a free rotation manner. The internal rotation member (3) includes: a disc-shaped internal rotation member body (3a) having crankshaft inserting through holes; and five outer circumferential convex parts (3f), integrally formed with the internal rotation member body (3a) and protruding to an outer circumferential side of the internal rotation member body (3a). The external rotation member (4) includes: a circular ring part configured on the internal rotation member (3) at an outer side of the outer circumferential convex parts (3f) in a free rotation manner; and five inner circumferential convex parts (4d), integrally formed with the circular ring part in a manner of protruding to an inner circumferential side of the circular ring part and configured alternately with the outer circumferential convex parts (3f). Elastic deformation parts (6) are configured between the outer circumferential convex parts (3f) and the inner circumferential convex parts (4d) on a rotation direction side of the advancing outer circumferential convex parts (3f). The outer circumferential convex parts (3f) are formed in such a manner that a surface on the rotation direction side is greater than a surface on an opposite side of the rotation direction.
