Claims

[Scope of claim for utility model registration] In a steering device in which a steering shaft passed through a column tube is supported by the column tube via a rolling bearing, one end of the inner ring of the rolling bearing is fixedly provided to the steering shaft. A second locking portion is fixedly provided at a portion of the outer circumferential surface of the steering shaft that is in contact with the first locking portion and is a predetermined distance away from the other end of the inner ring.
A small diameter portion having a smaller diameter than the inner diameter of the inner ring is formed in a portion between the locking portion and the middle portion of the width of the inner ring, and a portion between the second locking portion and the inner ring around the small diameter portion,
An anti-rattle ring made of a rubber-like elastic material and having an outer diameter larger than the inner diameter of the inner ring is interposed in a compressed state between the inner ring and the second locking part, and a part of the ring is inserted into the inner ring. A steering device that is inserted between the inner circumferential surface of the inner ring and the outer circumferential surface of the small diameter part and is in pressure contact with the inner circumferential surface of the inner ring.
