ABSTRACT:
A yoke of a universal joint for a steering apparatus, the yoke including a coupling member made by press-shaping a metallic plate and formed into the shape of a tube having a split in a circumferential portion thereof and a serration on an inner peripheral surface thereof. The coupling member has one end portion, having a partially cylindrical portion and a pair of flange portions integral with the partially cylindrical portion with the split interposed therebetween, and a substantially cylindrical coupling portion at another end portion thereof. Notably, the substantially cylindrical coupling portion has a larger outer diameter than an outer diameter of the partially cylindrical portion. The coupling member further includes a threaded hole formed in one of the flange portions, and a through hole formed in the other of the flange portions and coaxial with the threaded hole for passing a bolt to be threadably engaged with the threaded hole. A coupling arm made by press-shaping a metallic plate into a U-shape and having coaxial circular holes in opposite end portions thereof and having a coupling portion on a base portion thereof is provided. A bellows has one end portion fitted onto and welded to the coupling portion of the coupling member and another end portion fitted onto and welded to the coupling portion of the coupling arm. The yoke can be made very durable and can provide good shock absorbing capability.
