Steering wheels are steered by reciprocating the rack. FIG. 13A shows a conventional supporting device for supporting the rack 101. The support device includes a support member 104 that is inserted into a guide hole 103 formed in the rack housing 102 and is guided back and forth (in the left-right direction in the figure) by the inner peripheral surface of the guide hole 103. The guide hole 103 is formed so that the inner peripheral surface can be arranged on a virtual first cylindrical surface having an axial center along the front-rear direction. The support member 104 is formed so that its outer peripheral surface can be arranged on an imaginary second cylindrical surface whose axis is smaller in diameter than the first cylindrical surface and extends in the front-rear direction. The front end side of the support member 104 is a support surface that is depressed according to the curvature of the back surface of the rack 101, and the back surface of the rack 101 is supported via the sheet 105 by the support surface.

The side is a supporting surface. A concave portion 106 is formed on the rear end side of the support member 104 so as to extend between the two divided pieces 104a and 104b, and a pressure receiving surface along a conical surface which is inclined in the concave portion 106 toward the inner peripheral surface of the guide hole 103 as going rearward. 106a

くなるのを防止している。[0004] By pressing the teeth of the rack 101 against the teeth of the pinion by the support member 104, backlash is eliminated and smooth rotation transmission is achieved.
04 reciprocates in the front-rear direction to absorb the bending of the rack 101 and the processing tolerance at the time of gear cutting. By restricting the moving distance of the support member 104 rearward with respect to the rack 101 to a set range via the pressing member 107, poor engagement between the rack 101 and the pinion due to the excessive moving distance is prevented. Each divided piece 104
By pressing the a and 104b against the inner peripheral surface of the guide hole 103, the backlash of the support member 104 is prevented, the followability of the movement of the rack 101 with respect to the rotation of the pinion is reduced, and the teeth of the rack 101 and the pinion are rotated. This prevents the sound of collision with the teeth from increasing.

13 is pressed against the inner peripheral surface of the spring by the elastic force of the spring 108, as shown in FIG.
The outer peripheral surface of each of the a and 104b makes line contact with the inner peripheral surface of the guide hole 103 only at one location, and the outer peripheral surface of each of the divided pieces 104a and 104b and the guide hole 10
A gap w is generated between the inner peripheral surface of No. 3 and the inner peripheral surface. Then, since each of the divided pieces 104a and 104b starts to rotate as indicated by the arrow in the drawing from the contact point P with the inner peripheral surface of the guide hole 103, the support of the rack 101 by the support member 104 becomes unstable. , Rack 1 against pinion rotation
01, the followability of the movement of the rack 101 decreases, and the sound of collision between the teeth of the rack 101 and the teeth of the pinion increases.

Therefore, each divided piece can be prevented from rotating starting from a contact point with the inner peripheral surface of the guide hole, and the support of the rack by the support member can be stabilized. Therefore, it is possible to prevent the ability to follow the movement of the rack with respect to the rotation of the pinion from deteriorating, and prevent the sound of collision between the teeth of the rack and the teeth of the pinion from increasing.
