A rolling surface of each ball 11 and a radially outside surface of an inside guide plate 17 are in contact with each other only at two circumferentially set-apart inside contact parts 28a 28b, and portions of a radially inside surface of the inside guide plate 17, which correspond to the respective inside contact parts 28a, 28b, are supported by an outer surface of an inner-side concave groove 12a. The rolling surface of each ball 11 and a radially inside surface of the outside guide plate 18 are in contact with each other only at two circumferentially set-apart outside contact parts 36a, 36b, and portions of a radially outside surface of the outside guide plate 18, which correspond to the respective outside contact parts 36a, 36b, are supported by an inner surface of the outer-side concave groove 14a. At a state after the extensible rotation transmission shaft is assembled, at least the inner surface of the outer-side concave groove 14a is elastically deformed more radially outwards than a state before the assembling, thereby preloading each ball 11.
