ABSTRACT:
A grease nipple includes a fixture, a plurality of nipples arranged in radial directions around the circumference of the fixture and fixed thereto, and a screw projecting at one side of the fixture and tapering in a direction away from the fixture. A grease feed passage is formed through the fixture and the screw for feeding grease to a universal joint spider. A clamp portion is further provided between the fixture and the screw. The clamp portion has a width, as measured between the fixture and the screw, to provide a spacing between the fixture and the universal joint spider for receiving a thickness of a grease feed pipe between one of the nipples and the universal joint spider when the grease nipple is attached to the universal joint spider via the screw. The clamp portion may be formed integral with the fixture and the screw.
