PROBLEM TO BE SOLVED: To prevent the distribution of extra adhesive when an adhesive is used as a means for fixing a bearing sleeve to a housing. SOLUTION: A recessed adhesive agent sump U is formed in the inner peripheral surface 7c of the housing 7. The adhesive agent sump U is formed in the inner peripheral surface 7c of the housing 7 in a circumferential groove shape, and its both side areas in the axial direction are formed of tapered surfaces U1. Since the adhesive agent sump U is provided in the inner peripheral surface 7c of the housing 7, even when the extra amount of the adhesive agent T is produced depending upon a coated amount, its extra adhesive agent is caught by the recessed adhesive agent sump U, and the distribution of the adhesive agent T which affects the positioning of the bearing sleeve 8 and affecting a bearing performance is prevented.
