    摘要： A fixed type constant velocity universal joint, including: an outer joint member (11) having a cup shape; an inner joint member (12), which is received in the outer joint member (11), and is configured to transmit torque between the outer joint member (11) and the inner joint member (12) through intermediation of balls (13) while allowing angular displacement; and a shaft (15), which is coupled to the inner joint member (12) so as to allow torque transmission. A recessed portion (29) is formed in a bottom portion (18) of the outer joint member (11), and an embedded stopper (28) that enters the recessed portion (29) of the outer joint member (11) is mounted to a shaft end portion (24) of the shaft (15) opposed to the recessed portion (29). The embedded stopper (28) is allowed to interfere with the recessed portion (29) of the outer joint member (11) at an angle that is smaller than an incorporating angle of the balls (13) and larger than a maximum operating angle during use of the joint.

    摘要： A vented gaiter (6) for mounting to a shaft (4) comprises: a rim (34) defining an opening (33) for receiving the shaft (4); and a separate venting element (40). The venting element (40) is disposed within said opening (33). The shaft (4) is received in the opening (33), and the rim (34) is mounted to the shaft by means of a circular clamp (22). The venting element (40) is thus retained in place between the shaft (4) and the rim (34) and allows any air accumulated inside a CV joint enclosure (28) formed by the gaiter (6) when the gaiter (6) is mounted to the shaft (4) to vent axially according to a direction substantially parallel to the shaft longitudinal axis. The venting element (40) comprises a gas-permeable liquid-impermeable membrane (41).

The constant velocity universal joint is of a tripod type constant velocity universal joint. The track grooves extend in an axial line direction. Each of the track grooves comprises the guide surfaces opposed to each other and a large inner diameter section formed between the guide surfaces. The high-frequency heat treatment coil comprises a body section, wherein the body section comprises three heating sections including a pair of vertical frames, three upper frames connecting upper portions of the vertical frames, and three lower frames connecting lower portions of the vertical frames. The body section further comprises an upper opening opposed to the large inner diameter section, and a lower opening opened in an axial direction, wherein the body section being machined in an integrated manner. The upper opening is covered by a cover member and the lower opening is also covered by a cover member. The guide surfaces and the large inner diameter section in the vicinity of the guide surfaces being thermally treated by the vertical frames of the three heating sections.

    摘要： In an outer joint member (11) of a constant velocity universal joint, which is formed by welding a cup member (12a) and a shaft member (13a) to each other, the cup member (12a) and the shaft member (13a) are made of medium to high carbon steel. The cup member (12a) has a bottomed cylindrical shape that is opened at one end, and includes a cylindrical portion (12a1), a bottom portion (12a2), and a short shaft section (12a3) of a solid shaft shape protruding from the bottom portion (12a2) and having a joining end surface (50) formed at an end portion. The shaft member (13a) has a solid shaft shape and has a joining end surface (51) at one end. The joining end surface (50) of the cup member (12a) and the joining end surface (51) of the shaft member (13a) are brought into abutment against each other, and a high energy intensity beam is radiated from an outer side in a radial direction to form a welded portion (49). A structure of a molten metal at the welded portion (49) is in a mixed phase of ferrite and granular cementite. With this, a crack is prevented at a welded portion of an outer joint member of a constant velocity universal joint in which a cup member and a shaft member are welded.
