の固定金具。 A bearing fixing fitting that fixes the bearing 4 to the shaft support member 2 having a bearing support hole 21, which can be inserted into the support hole 21 and is used to secure the outer ring 4 of the bearing 4.
A cylindrical wall portion 6 having an abutment portion 60 that abuts on the side wall of 1
1 and a closing wall portion 62 for closing the support hole 21;
A tapered stopper body 7 has an outer periphery that can be inserted into the holder 6, and the outer periphery can be elastically expanded in diameter under a predetermined load. A sealing means is interposed between the cylindrical wall portion 62 of the holder 6 and the inner peripheral surface of the support hole 21, and an insertion hole 72 for the screw shaft 8 is formed in the stopper body 7. By tightening the nut 9 screwed onto the screw shaft 8, the screw shaft 8 is tightened.
A bearing fixing fitting characterized in that the holder 6 is fixed to the support hole 21 by pressing the outer circumference of the stopper 7 inserted through the support hole 21 into pressure contact with the inner circumference of the support hole 21.
