However, there is a gap between the cage and the inner joint member that allows relative movement for a certain distance in the axial direction, and the cage is held at a neutral position with respect to the inner joint member by the elastic member. The vibration is absorbed by the cage and is not transmitted between the cage and the inner joint member.

。With the above configuration, this constant velocity joint transmits torque at an arbitrary angle because the cage 3 holds the ball 4. At this time, the elastic member 5 is connected to the spherical end of the driven shaft A.
Since the cage 3 is movable, the cage 3 and the inner joint member 1, that is, the driving shaft B and the driven shaft A can have any angle. In this torque transmission state, torque is transmitted from the driving shaft B to the driven wheel A by the entire plurality of balls. Also,
Vibration from the driving shaft B is transmitted to the inner joint member 1 via the ball 4 and the ball holding window 3a of the cage 3. However, there is a gap between the cage 3 and the inner joint member 1 that allows relative movement for a certain distance in the axial direction, and the cage 3 is held at a neutral position with respect to the inner joint member 1 by the elastic member 5. Therefore, vibrations are absorbed by the elastic member 5 and are not transmitted between the cage 3 and the inner joint member 1. Furthermore, the balls 4 do not come into firm contact with the inner circumferential surface of the ball holding window 3a, and vibrations are not transmitted between the balls 4 and the cage 3.

維持することができる。[Modified example] As shown in Fig. 2, the constant velocity joint of this modified example has an inner joint member 1 provided at one end of the driven shaft A and an outer joint member integrally fixed to one end of the driving shaft B. It consists of a outer joint member 2, a cage 3 fitted between the inner joint member 1 and the outer joint member 2, and a ball 4 held in the cage 3,
This configuration is the same as the embodiment. The difference is that the elastic member 5, stopper member 51, bolt 52, and ring 53 used in the embodiment are not used, and a spring member 6 as shown in FIGS. 2 and 3 is used. The spring member 6 is a belt-shaped plate wound spirally, and the outermost ring is held in a recess at the inner peripheral end of the cage 3, and the innermost ring is held in a recess at the tip A1 of the driven shaft A. This spring member 6 bends when the cage 3 and the inner joint member 1 rotate relative to each other, and uses this elastic force to hold the cage 3 in a neutral position with respect to the inner joint member 1, and also maintains the cage 3 and the inner joint member 1 in a neutral position. No vibration is transmitted between the member 1 and the member 1. The ball 4 can be roughly maintained in the center of the ball holding window 3a.

In a constant velocity joint in which a window holds a ball for transmitting torque, a gap is provided between the cage and the inner joint member to allow relative movement by a certain distance in the axial direction, and further, the cage and the inner joint member are provided with a gap that allows relative movement by a certain distance in the axial direction. By interposing an elastic member that restricts relative movement in the axial direction between the cage and the inner joint member, the cage is forcibly held in a neutral position with respect to the inner joint member. Vibration transmitted between the members is reduced, and there is less surrounding resistance between the cage and the inner and outer joint members, and less noise is generated.
