<p><P>PROBLEM TO BE SOLVED: To easily and precisely form a clearance allowing movement in the center axis direction of a shaft in a bearing mechanism. <P>SOLUTION: In a method for manufacturing the bearing mechanism 4 used for a motor of a storage disk drive apparatus, a sleeve 42 in which the shaft 41 is inserted and a seal member 44 are fitted in a sleeve housing 43 and slidably and temporarily fixed, a lower end 411 of the shaft 41 abuts on a thrust member 45 arranged on an inner bottom surface of the sleeve housing 43, and the sleeve 42 abuts on a detent member 412 of the shaft 41. Since a bottom 432 of the sleeve housing 43 is pressed and elastically deformed, the shaft 41, a sleeve 42, and the seal member 44 are moved on an opening side of the sleeve housing 43 through a thrust member 45, and pressing is released to return the bottom 432 to an original shape. Therefore, the axial clearance 46 in which the shaft 41 can move is easily and precisely formed between the sleeve 42 and the detent member 412. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
