プライン５に密着される。First, a conventional manufacturing method will be explained with reference to FIGS. 5(a) to 5(d). A mold release agent is applied to the female spline 2 of the yoke 1 (a). Next, the monomer liquids A and B are mixed and flowed into the female spline 2 and stored (b). The storage amount is the amount necessary to form a resin film (described later). 3 indicates a storage jig. On the other hand, the male spline 5 of the shaft 4 is soaked in the primer 6, and the primer 6 is applied to the structural surface (c). Finally, the male spline 5 is inserted into the female spline 2, and the mixed solution of the seven-mer liquid A and B is spread over the entire surface facing each other and heated. Polymerization is started by this heating, and a resin film 7 is formed (d). This resin film 7 is formed by applying a primer 6 to the male spline 5,
By applying a mold release agent to the female spline 2, it is brought into close contact with the male spline 5.

、ここに樹脂膜７が密着している。FIG. 3 shows an enlarged sectional view of the main part of the slide spline manufactured by the above manufacturing method. The male spline 5 is usually manufactured using a gear cutting machine or a rolling tool, and the female spline 2 is generally manufactured using a broaching machine. Therefore, the surface of the female spline 2 has a convex portion 8 due to the broach surface being torn off.
There is a concave portion 9 in the resin film 7 corresponding to the convex portion 8 . On the other hand, the surface of the male spline 5 is formed into a smooth surface, and the resin film 7 is in close contact with the surface.

と両スプライン２．５が凝着する問題がある。However, in the slide spline, when the male spline 5 and the female spline 2 are slid relative to each other, the resin film 3 is scraped by the convex portion 8, so that a gap 11 is created as shown in FIG. 4. This gap 11 has the problem of increasing backlash between both splines 2.5. Further, there is a problem in that foreign substances such as sand and water enter, further increasing wear on the resin film 7. When the resin film 7 is severely worn, there is a problem that both splines 2.5 stick together.
