<p>The flatness of portions which face a gap within a thrust bearing formed from a resinous material is easily heightened. A housing (7) is an injection-molded object formed from a resinous material and has a bottomed cylindrical shape comprising a cylindrical lateral part (7a) and a flat bottom part (7b) integrated therewith. The resinous material for use in injection-molding this housing (7) contains, as a filler, reinforcing fibers having a fiber diameter of 6-8 µm and an aspect ratio of 10-40.</p> |
