Abstract

The present invention comprises an outer race member including an outer race groove portion that is provided at an inner periphery of the outer race member formed into a cylindrical shape, in a recessed manner so as to be angled to a rotational axis of a constant velocity joint, a first outer race groove end portion situated on a first propeller shaft side of the outer race groove portion, and a second outer race groove end portion situated on a second propeller shaft side of the outer race groove portion; a ball member disposed in the outer race groove portion; and an inner race member provided on an inner peripheral side of the outer race member and connected to the second propeller shaft of a propeller shaft, the inner race member including an inner race groove portion provided at an outer periphery of the inner race member in a recessed manner so as to be angled to the rotational axis of the constant velocity joint and intersect with the outer race groove portion, the inner race groove portion being formed to have a larger outer diameter than the second propeller shaft, a first inner race groove end portion situated on the first propeller shaft side of the inner race groove portion, and a second inner race groove end portion situated on the second propeller shaft side of the inner race groove portion. Distance from a position at which the ball member is situated in the outer race groove portion to the first outer race groove end portion of the outer race groove portion is set longer than distance from a position at which the ball member is situated in the inner race groove portion to the second inner race groove end portion of the inner race groove portion.
