ABSTRACT:
A structure of a universal joint is disclosed in which an end surface of a spider is coated with a solid lubricant and a projection having an arc cross section formed on a center of a bearing cup into which the spider is fitted is brought into point contact with the solid lubricant coated end surface of the spider. When the spider is axially rotated, the friction generated on the bearing cup can be remarkably reduced.
