摘要

Easy and precise setting of a predetermined thrust bearing gap is made possible. An axial gap 13 having a dimension that is equal to the sum of two thrust bearing gaps is first provided between the flange part 2b of the shaft member 2 and the bearing member or bearing sleeve 8. The shaft member 2 and the bearing sleeve 8 are accommodated inside the housing 7 with this gap dimension delta being kept, and the bearing sleeve 8 is secured to the housing 7.
