Claims

[Claims for Utility Model Registration] 1. Each shaft end of the cross shaft is supported by a pair of yokes via a bearing, and a supply hole is provided for supplying lubricant from the shaft intersection of the cross shaft to each bearing. In the lubricant supply device of the universal joint formed through the cross shaft, one end is connected to the lubricant delivery side via a first swivel joint attached to the outer periphery of the one yoke. , the other end is provided with a flexible introduction pipe for introducing lubricant, the other end of which is connected to the supply hole via a second swivel joint attached to the axis intersection part, The swivel joint supports one end of the introduction pipe so as to be rotatable around an axis parallel to the axis of relative rotation between the one yoke and the cross shaft, and the second swivel joint supports the one end of the introduction pipe. A universal joint lubricant supply device, characterized in that the other end of the introduction pipe is supported rotatably around an axis perpendicular to the relative rotation axis. 2 The first swivel joint supports one end of the introduction pipe so as to be rotatable around the relative rotation axis, and the first swivel joint is made of a rigid body instead of the flexible introduction pipe. The lubricant supply device for a universal joint according to claim 1, which uses an introduction pipe.
