<P>PROBLEM TO BE SOLVED: To easily and stably secure fixing strength and fixing accuracy required between a housing and a bearing sleeve. Ž<P>SOLUTION: Engaging parts 12 and 12 extending in the radial direction and respectively engaging in the axial direction with an upper end part and a lower end part of the bearing sleeve 8, are separately arranged in two places in the axial direction in the housing 7. An upper side end surface 8b of the bearing sleeve 8 engages with a seal part 7b as an upper side engaging part 12, and a lower end outer peripheral chamfer 8fo of the bearing sleeve 8 engages in the axial direction with a projection part 7c as a lower side engaging part 12. Such a constitution can regulate the movement to both sides in the axial direction of the bearing sleeve 8 without interposing an adhesive between the bearing sleeve 8 and the housing 7.
