A rotation transmitting apparatus in which a cylindrical surface 2a is formed on the inner surface of an outer ring 2; an input shaft 4 is rotatably supported in the outer ring 2; a plurality of cam surfaces 6 for forming the wedge-shaped spaces cooperating with the cylindrical surface 2a are formed on the input shaft 4; rollers 9 are held in the cage 7 for engageable the cylindrical surface2a and the cam surface 6 due to relative rotation between the outer ring 2 and the input shaft 4; a two-way clutch "C" has a switching spring 12 for keeping the rollers 9 at their neutral positions; an armature 13 is arranged at one end of the cage 7 so as not to be rotated relative to the cage 7; a friction applying means comprises the end surface of the armature 13; an inclined surface 16 opposed to the end surface and extending radially outward gradually toward the end surface of the armature 13; and a plurality of weights 19 arranged within an annular space formed between the end surface 13b of the armature 13 and the inclined surface 16. <IMAGE> |
