    摘要: In a universal joint, a cross shaft member includes four shaft parts forming a cross-shape. Each of four bearing cups corresponding respectively to the shaft parts has a hollow-cylindrical shape having a bottom and is rotatably mounted to the corresponding shaft part through a roller disposed between an inner peripheral surface of the each bearing cup and an outer peripheral surface of the corresponding shaft part. Each bearing cup includes an inner bottom surface in sliding contact with a distal end surface of the corresponding shaft part, wherein the sliding contact is in an annular region encompassing a central axis of the corresponding shaft part. The distal end surface of each shaft part is formed with an annular groove encompassing the central axis of the first shaft part for storing oil.
