Claims

[Scope of utility model registration request]

an outer member coupled to a first shaft, the outer member having at least three grooves extending in the axial direction of the shaft at equal intervals in the circumferential direction; and a rail extending in the axial direction of the first shaft; an outer member projecting radially inward into each of the grooves; and an inner member coupled to a second shaft, the axis of the second shaft projecting into each of the grooves; an inner member having a roller shaft extending outward in the radial direction and having a convex spherical surface on the outer periphery, a concave spherical surface on the inner periphery and a cylindrical surface on the outer periphery, the concave spherical surface fitting into the convex spherical surface; The cage is attached to each of the roller shafts, and has two notches facing the rails, into which the rails of the outer member are fitted, and which are cut out so as to diverge from the inner peripheral surface to the outer peripheral surface. and a roller rotatably supported by each cage and in contact with the outer member, and when the first shaft and the second shaft rotate at a joint angle, the A regulating means is configured together with the rail to keep the cage and the rollers in an unchanged posture with respect to the axis of the first shaft, and the cage and the rollers are arranged in a radial direction perpendicular to the axis of the first shaft. Sliding constant velocity joint that allows relative movement.
