SPHERICAL SLIDING BEARING, BEARING UNIT WITH ALIGNING FUNCTION, AND BEARING DEVICE FOR STEERING COLUMN

摘要

PROBLEM TO BE SOLVED: To provide a spherical sliding bearing capable of realizing smooth steering operation by reducing oscillating torque of a steering shaft.

SOLUTION: In this spherical sliding bearing 34 comprising an outer ring 36 provided with a concave spherical portion 38 on its inner peripheral face, and an inner ring 37 provided with a convex spherical portion 42 slid to the concave spherical portion 38 on its outer peripheral face, a non-contact portion 50 is formed on sliding faces of the concave spherical portion 38 and the convex spherical portion 42.
