PROBLEM TO BE SOLVED: To easily take in lubricant existent on an inner side in the radial direction of a washer 6 into passages 19a, 19a formed among bottom faces of channels 18a, 18a provided on both side faces of a washer 6a and a tip face of an end part 7 of a cross shaft and a bottom face of a bearing cup 4 to hold a satisfactory lubrication condition of a slide contact part of both side faces, the tip face, and the bottom faces. SOLUTION: Inside diameter d<SB>6a</SB>of the washer 6a is set to be smaller than diameter d<SB>9</SB>of an opening part formed on the tip face and diameter d<SB>14</SB>of an opening part formed on the bottom face (d<SB>6a</SB><d<SB>9</SB>≈d<SB>14</SB>). Chamfered parts 20, 20 are formed in inner peripheral fringe parts of both side faces of the washer 6a to enlarge opening area on an inner side in the radial direction of each passage 19a, 19a.
