PROBLEM TO BE SOLVED: To prevent creep wear by providing possibility of fixing a bearing certainly without pressure fitting and adhesion. SOLUTION: The outer ring 8B of a rolling bearing 8 is fitted in a cylindrical housing 21 formed ptotrusively on a bracket 16 for fitting-in of the bearing, wherein a tapered surface 22 enlarging diameterically from tip 21a side to base end 21b side is formed on the periphery of the housing 21. A plurality of slits 23 are provided at the periphery of the housing 21 in the circumferential arrangement. A pressure ring 24 is fitted on the housing 21 and fastened by a bolt 28 so that the housing 21 is contracted diameterically, and thus the bearing 8 is secured. |
