Each of the first track groove portions includes an arc-shaped ball raceway center line having a curvature center prevented from being offset in an axial direction of the outer joint member with respect to a joint center. Planes each including at least the ball raceway center line and the joint center are inclined with respect to a joint axial line with their inclination directions opposite to each other in the first track groove portions, which are adjacent to each other in a peripheral direction of the outer joint member. Each of the second track groove portions includes a ball raceway center line having a straight part when being projected onto corresponding one of the planes.

摘要： To make a bellows section of a boot to be flexibly and repeatedly deformable without deterioration in durability, to thereby reduce rotational resistance when a joint angle is large, the boot has the bellows portion where three or more circumferentially extending crest portions and root portions therebetween are alternately formed. A large-diameter attaching portion is formed at one end of the bellows portion. A small-diameter attaching portion is formed at the other end. A rising wall closest to the large-diameter attaching portion and a rising wall closest to the small-diameter attaching portion have smaller wall thickness than other portions of the bellows section. A ratio (t1/t2) of the thickness (t1) of the rising walls to the thickness (t2) of the other portions of the bellows portion is set to 0.6≦t1/t2

摘要： A constant velocity universal joint shaft, capable of suppressing a rotational backlash when incorporated in the constant velocity universal joint, and improving the assembly efficiency as well as reducing the manufacturing cost. A constant velocity universal joint shaft has a spline that fits an inner race of the constant velocity universal joint. The shaft includes a shaft body with a spline formed thereon, and a yoke portion with a ring-shaped fitting portion. The shaft body and the yoke portion are integrally formed of medium carbon steel. By a pressing force of a pressing member the fitting portion of the yoke portion is tightened, so that such fitting portion fits a shaft external to the joint. In the constant velocity universal joint, the pressing member and an abutment member are elastically butted via an elastic member, so that a ball constantly remains in contact with a raceway of an outer member and a raceway of an inner member.

摘要： The tripod member has three trunnions which are projected radially. Each of the trunnions carries a roller, and this roller is accommodated in one of the track grooves in the outer joint member. The outer peripheries of the rollers and the roller guideways make angular contact with each other. Support rings are fitted onto the outer peripheries of the trunnions. These support rings and the rollers are assembled (unitized) via a plurality of needle rollers to constitute roller assemblies capable of relative rotations. In longitudinal sections, the outer peripheries of the trunnions have straight shapes parallel to the axes of the trunnions. In cross sections, the outer peripheries are elliptic in shape, with their respective major axes perpendicular to the axis of the joint. The inner peripheries of the support rings have arcuate convex sections.
