Claims

[Claims for Utility Model Registration] Consisting of a pair of hubs 1 attached to the driving shaft 8 or the driven shaft 9, and a spacer 2 that transmits the rotation between the two hubs 1, the spacer 2 faces the both hubs 1. The fitting parts 5 formed on both end faces of the spacer 2 and the fitting parts 4 formed on the end faces of both hubs 1 facing the spacer 2 can be slid against each other in a direction perpendicular to the axes 8a and 9a. In an Oldham shaft joint in which the sliding direction of one hub 1 and spacer 2 and the sliding direction of the other hub 1 and spacer 2 are slightly different from each other, both ends of spacer 2 are fitted. On the surface and the end surfaces of both hubs 1,
Sliding surfaces 1a, 4 that receive forces in the directions of the axes 8a, 9a
a, 4b, 5a, 6a, and at least one of the opposing sliding contact surfaces 1a, 4a, 4b, 5a, 6a has a spacer 2 and a hub 1. An Oldham shaft joint characterized in that it is provided with a rotation fulcrum part Q that allows the and the parts to rotate slightly relative to each other.
