Claims

[Scope of utility model registration request]

A female spline having female spline teeth on the inner periphery of the cylindrical body, and a male spline tooth inserted into the female spline near the tip and meshing with the female spline teeth so as to be slidable in the axial direction and non-rotatable around the axis. and a male spline having a cylindrical surface on the opposite side of the tip from the male spline teeth, and in which a nylon film is formed on at least the male spline teeth of the male spline, the male spline is inserted into the female spline, and the male spline is On the cylindrical surface of the cylindrical surface, at a position corresponding to the opening end of the female spline, a centering spigot diameter portion having an outer circumferential surface that fits the spigot to the minimum diameter of the female spline tooth is formed to bulge out, and at the tip of the male spline, the female spline is attached to the female spline. A widening taper whose center line coincides with the center line of the female spline at the tip facing the male spline, which is inserted into the cylindrical shaft to be connected and fixed during the formation of the nylon film and removed after the nylon film is formed, and an open end of the taper. A jig having a flat surface substantially perpendicular to the center line is formed with a converging retaper at the distal end that engages with the widening taper at the distal end, and in a portion surrounded by the taper at the tip of the male spline, the female spline, and the flat surface of the jig. A sliding spline characterized in that the formed ring-shaped nylon portion is fixed to the male spline integrally with a nylon film formed on the male spline teeth.
