PROBLEM TO BE SOLVED: To provide a resinous bearing improved in strength to bearing pressure, friction resistant characteristic to shaft movement, friction characteristic, and precision characteristic of cylindricalness. SOLUTION: On the outside surface and/or inside surface of a resinous bearing 1, a constituting material is spirally or circumferentially oriented. The bearing has a cylindrical or columnar form, and as the resin, a thermoplastic resin, particularly a thermotropic liquid crystal polymer is preferably used. The outside and/or inside orientation of the bearing can be formed by rotating at least one of metal mold components for forming the outside and inside of the bearing in the circumferential direction in injection filling of the fused resin of the material into a mold. |
