Abstract
Abstract A supporting structure for a steering apparatus of the rack and pinion type with a rack axle supporting member. The supporting member is supported on a vehicle body by a clamping member through mounting insulators. This insulator comprises a first elastic means to receive smaller input forces by means of shearing stress and a second elastic means to receive larger input forces by means of compressive stress.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
116 words
A supporting structure for a steering apparatus of the rack and pinion type comprising a rack axle supporting member which includes a rack tube and a gear housing adapted to axially movably support a rack axle, a mounting insulator provided around said rack axle supporting member, a clamping member around said mounting insulator for supporting said rack axle supporting member onto a vehicle body via said insulator, said mounting insulator comprising a first elastic means adapted to receive axial displacement forces applied to said rack axle supporting member by means of shearing stress and a second elastic means adapted to receive axial displacement forces applied to said rack axle supporting member by means of compressive stress.
Claim 2
Dependent Claim
116 words
A supporting structure for a steering apparatus of the rack and pinion type comprising a rack axle supporting member which includes a rack tube and a gear housing adapted to axially movably support a rack axle, a mounting insulator provided around said rack axle supporting member, a clamping member around said mounting insulator for supporting said rack axle supporting member onto a vehicle body via said insulator, said mounting insulator comprising a first elastic means adapted to receive axial displacement forces applied to said rack axle supporting member by means of shearing stress and a second elastic means adapted to receive axial displacement forces applied to said rack axle supporting member by means of compressive stress.
Claim 3
Dependent Claim
26 words
The supporting structure as claimed in claim 1, wherein said supporting member is provided with a pair of flanges between which said mounting insulator is positioned.
Claim 4
Dependent Claim
28 words
The supporting structure as claimed in claim 2, wherein said pair of flanges face an elastic portion or member of the second elastic means with a gap therebetween.
Claim 5
Dependent Claim
50 words
