PROBLEM TO BE SOLVED: To easily and firmly stick a sealing member and a sleeve member to each other and, at the same time, to dissolve the problem of the productivity drop of a motor. SOLUTION: A lubricating fluid 9 is injected into the outer peripheral end section of the thrust fluid dynamic bearing section 10 of a thrust plate 4 from the outside through the first lubricating fluid injecting hole 17 of a top cover 14, an annular lubricating fluid storage chamber 16, and the second lubricating fluid injecting hole 18 of a thrust bush 15 after the contacting surfaces of the top cover 14 and thrust bush 15 are fixed to the contacting surface of a sleeve member 7 with an adhesive. Consequently, a sealing member 8 and the sleeve member 7 can be easily and firmly stuck to each other, because the lubricating fluid 9 does not enter between the stuck surfaces of the cover 14 and bush 15 and that of the member 7 as in the case of conventional example. In addition, the productivity of a motor does not drop, because the sticking does not take time. |
