<p>PROBLEM TO BE SOLVED: To provide a structure that can sufficiently secure durability of a radial bearing by making a contact condition between the radial bearing and a revolving shaft uniform in an axial direction.SOLUTION: In a rotation support device, a shell-shaped outer ring 10 is press-fitted and fixed to the inside of a cylindrical holding part 19, and the revolving shaft is rotatably supported to the inside of the outer ring 10 via a plurality of needles. Stiffness of a tip of the holding part 19 is secured by a flange part 20 formed on the outer peripheral surface thereof. An inner diameter of the holding part 19 is controlled to be constant across one axial end to the other axial end while the outer ring 10 is fitted and fixed into the holding part 19.</p> |
