Abstract
A universal joint includes a yoke having a fitting portion for fitting a shaft. The fitting portion has first and second tabs opposed to each other to form a U shape. A fixing mechanism including a bolt passing through respective insertion holes in the first and second tabs and a nut screwed onto the bolt on a fastening axis fastens and fixes the shaft between the first and second tabs. A nut holding member fixed to the second tab has an engaging piece. The engaging piece causes the nut, which has not been screwed onto the bolt, to be held on the fastening axis. A cover held by the nut holding member covers at least the engaging piece around the nut.
