Abstract
A rotation transmission device includes a control retainer and a rotary retainer having bars arranged circumferentially alternating with each other such that pockets are defined between the adjacent pairs of bars. A pair of rollers are mounted in each pocket with an elastic member disposed between the pair of rollers such that the pair of rollers are pushed by the respective bars to their respective disengaged positions when the control retainer and the rotary retainer rotate relative to each other. A spring holder is fitted on an input shaft while abutting one axial end surface of an inner ring. The spring holder has spring support pieces on the outer periphery thereof to prevent radially outward movement of the elastic members. The spring support pieces are plate-shaped members disposed radially outwardly of the elastic members to extend in the axial direction in parallel to the outer periphery of the inner ring.
