Claims

[Scope of utility model registration request]

An outer race is formed in a cylindrical shape and has a ball groove formed in the width direction on the inner circumference, and an outer race is arranged concentrically with the outer race, and the outer circumference surface is formed in a convex arc shape in the axial cross section. an inner race in which a groove is formed, a ball interposed between the outer race and the inner race and engaged in the respective ball grooves, and an outer peripheral surface in an axial cross section interposed between the outer race and the inner race. a cage having a convex arc shape, an inner circumferential surface formed in a concave arc shape to fit into the convex arc outer circumferential surface of the inner race, and a hole in the axially intermediate portion into which the ball fits. , a double offset type constant velocity joint in which the respective radial centers of the convex arcuate outer circumferential surface of the inner race and the convex arcuate outer circumferential surface of the cage are arranged to be biased to opposite sides with the center of the ball in between, A double offset type constant velocity joint characterized in that an appropriate amount of clearance is provided between the convex arc-shaped outer circumferential surface of the cage and the inner circumferential surface of the outer race.
