PROBLEM TO BE SOLVED: To provide a boot attachment method capable of reducing the size and weight of a constant velocity universal joint by eliminating a boot band and capable of reducing cost required to assemble the constant velocity universal joint. SOLUTION: An attaching surface 21 of a large diameter end part 11 of the boot 10 and an attached surface 18 of a metallic outer ring 2 are overlapped and tightly contacted and arranged in an annular metal coil 150, an attaching surface 22 of a small diameter end part 12 of the boot 10 and an attached surface 19 of a metallic shaft 15 are overlapped and tightly contacted and arranged in an annular metal coil 160 and a high frequency current is applied to the metal coils 150, 160. In this case, depths of heating of the attached surface 18 of the outer ring 2 and the attached surface 19 of the shaft 15 are equal to or shorter than 0.1 mm from their surfaces and coating treatment is conducted before heating. The whole boot 10 is molded by thermoplastic polyester elastomer and added with carbon black. COPYRIGHT: (C)2009,JPO&INPIT
