Housing for fluid lubrication bearing apparatuses

Abstract

A housing for fluid lubrication bearing apparatuses having improved adhesiveness with other components is provided at low costs. A housing 7 constituting a fluid lubrication bearing apparatus 1 was formed of a resin composition comprising polyphenylene sulfide (PPS) as a base resin, and the ratio of the base resin added to the resin composition was set to not lower than 40 vol % but not higher than 70 vol %. Moreover, a composition prepared by adding an epoxy compound having two or more epoxy groups per molecule of the compound and epoxy value of 0.5 meq/g or more to the resin composition so that the amount of epoxy groups in the resin composition is 8 meq/100 g or more was used. A carbon fiber was added to the resin composition comprising the base resin in an amount of not less than 10 vol % but not more than 35 vol %. An inorganic compound was further added to the resin composition comprising the base resin and carbon fiber so that the inorganic compound makes up the remainder of the base resin and carbon fiber in the resin composition.
