Abstract

Abstract In a rack and pinion type steering system with an energy absorbing mechanism, errors in axial dimensions of the steering shaft and column tube often make it difficult to fix the two parts to each other at two predetermined axially spaced positions. Such difficulty is eliminated by providing an elongated slot of a predetermined axial length in the column tube to allow a holding member to extend radially through the slot irrespective of the dimensional errors to fixedly connect the column tube to the steering shaft. In addition, a support member which is mounted on the steering shaft for assembling a bearing thereon is constituted by a single structure to preclude disconnection or disintegration of component parts caused by the thrust acting thereon and provided with claw portions or caulking wall portions for holding the bearing securely in position.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 73 words
A steering shaft support device, comprising a steering shaft accommodated within a column tube, an elongated slot formed in a predetermined axial length in said column tube, a holding member mounted on said column tube for supporting said steering shaft through a bearing, said holding member being extended radially outward of said column tube through said slot, and fixing means for fixing said holding member on the outer periphery of said column tube.
Claim 2
Dependent Claim 73 words
A steering shaft support device, comprising a steering shaft accommodated within a column tube, an elongated slot formed in a predetermined axial length in said column tube, a holding member mounted on said column tube for supporting said steering shaft through a bearing, said holding member being extended radially outward of said column tube through said slot, and fixing means for fixing said holding member on the outer periphery of said column tube.
Claim 3
Dependent Claim 43 words
A steering shaft support device as defined in claim 1, wherein said holding member is adapted to support said bearing at one end thereof, having the other end fixed in position on the outer periphery of said column tube by said fixing means.
Claim 4
Dependent Claim 40 words
A steering shaft support device as defined in claim 1, wherein said holding member is adapted to support said bearing by opposite end wall sections thereof and fixed in position by said fixing means at an intermediate wall section thereof.
Claim 5
Dependent Claim 27 words
A steering shaft support device as defined in claim 2 or 3, wherein said fixing means is a bolt radially clamping said holding member in said position.
Claim 6
Dependent Claim 28 words
A steering shaft support device as defined in claim 4, wherein said holding member is provided with a hole of a predetermined axial length for receiving said bolt.
Claim 7
Dependent Claim 25 words
