PROBLEM TO BE SOLVED: To directly lubricate a raceway groove of a turning bearing by a lubricant-contained polymer, and to prevent the dropping of the lubricant-contained polymer by shrinkage. SOLUTION: The lubricant-contained circular polymer P2 (P3a) is fitted to an outer-diameter face of a spacer main body 30 (50). The spacer main body 30 is divided into two to hold the lubricant-contained polymer P1, P2. Or a projecting part P3b is formed from the lubricant-contained circular polymer P3a to a central part side of both concave spherical faces 52 to hold the spacer main body 50.
