Abstract

See full text

The rolling surface of each ball and a radially outside surface of the inside guide plate are in contact with each other only at two circumferentially set-apart inside contact parts. The rolling surface of each ball and a radially inside surface of the outside guide plate are in contact with each other only at two circumferentially set-apart outside contact parts. At a state after the extensible rotation transmission shaft is assembled, at least the inner surface of the inner-side concave groove is elastically deformed more radially inwards than a state before the assembling, thereby preloading the respective balls.
