Claims

[Scope of utility model registration request]

a cylindrical casing integral with a first shaft; and a concave spherical surface disposed within the casing via a low friction coefficient means and held movable in the axial direction of the first shaft and immovable in the circumferential direction. an intermediate casing having a plurality of first grooves having an arc shape in a virtual plane perpendicular to the axis of the first shaft, the concave spherical surface having a plurality of first grooves at equal intervals in the circumferential direction; is a second shaft having an intermediate casing formed in an arc shape in a virtual plane including the axis of the first shaft, and a convex spherical portion disposed within the intermediate casing, the second shaft being orthogonal to the axis of the second shaft. The convex spherical surface portion has the same number of second grooves as the first grooves, which have an arc shape on the virtual surface, and are spaced at the same intervals as the first grooves in the circumferential direction, and each groove has the same number as the first grooves. A second shaft formed in an arc shape in a virtual plane including the axis of the shaft, and a ball disposed in a space formed by each of the first grooves and the second groove facing the groove. Constant velocity universal joint.
