<P>PROBLEM TO BE SOLVED: To provide a mechanism for applying a preload to a rolling bearing suppressing the lowering of the preload or the release of the preload during a temperature rise. <P>SOLUTION: Thermal expansion members 12 and first pressure receiving members 11 or second pressure receiving members 13 are arranged throughout a circumferential direction between the front face of an outer ring and a wall face facing the front face of the outer ring in a housing. When the thermal expansion member 12 moves radially outward by thermal expansion caused by a temperature rise, both the pressure receiving members are pressed by wedge effect while sliding on the first pressure receiving member 11 or the second pressure receiving member 13, and generates a thrust preload force for the bearing. <P>COPYRIGHT: (C)2009,JPO&INPIT |
