PROBLEM TO BE SOLVED: To secure high adhesive strength when adhering and fixing another member to a resin housing. SOLUTION: A bearing sleeve 8 is fixed into the resin housing 7 and a shaft member 2 is supported in non-contact therewith in the radial direction with the dynamic pressure operation of lubricating oil generated in a radial bearing gap between the shaft member 2 and the bearing sleeve 8. Onto the outer periphery of the housing 7, a metal bracket 6 is adhered and fixed for mounting a stator 4 of a motor. In this case, an adhesive portion of the housing 7 to the bracket 6 is roughened with its surface roughness set to be 0.5-2.0μmRa. COPYRIGHT: (C)2005,JPO&NCIPI |
