る。(Prior Art) FIG. 1 shows a first conventional comparative example. The pinion teeth 1a of the pinion shaft 1 connected to the handle shaft mesh with the rack teeth 2a of the rack shaft 2 connected to the steering wheel, and the support yoke 3 supporting the back surface 2b of the rack shaft 2 is attached to the housing 4. A spring is slidably attached to a hole 4a perpendicular to the formed rack shaft 2, a screw 4b is cut into the base of the hole 4a, a yoke plug 5 is screwed, and the spring is installed in the rear hole 3a of the support yoke 3. 6 is supported by the yoke plug 5,
In order to ensure that the rack shaft 2 can slide smoothly even if there are heat treatment distortions or machining errors in the pinion teeth 1a and rack teeth 2a, etc., there is a slight gap between the rear end surface 3b of the support yoke 3 and the front end surface 5a of the yoke plug 5. A gap is provided. Here, the sliding resistance of the rack shaft 2 is caused by the necessary rotational torque of the pinion shaft 1 meshed with the rack teeth 2a, the frictional force between the support yoke 3 and the rear surface 2b of the rack shaft, and sometimes the frictional force with the rear surface 2b of the rack shaft. is large as a friction. This friction is determined by the friction coefficient between the rack shaft rear surface 2b and the support yoke 3 and the load of the spring 6.

た。 Therefore, in order to reduce friction, it would be better to reduce the load on the spring 6, but because of the need to maintain high handle rigidity, the pinion shaft 1 and the rack shaft 2
The load of the spring 6, which suppresses the axial displacement of the support yoke 3 due to the meshing component force, must be kept high and cannot be lowered. Therefore, methods of reducing the coefficient of friction on the support surface of the support yoke 3 have been considered, such as making the support yoke 3 from resin or coating the entire thing, but since the former is made entirely of resin, the support The yoke tips 3c and 3d are weakened, and the latter has the disadvantage that unnecessary parts are coated, making it expensive.

ある。 FIG. 2 shows a second conventional comparative example, in which a groove 13d of a constant depth is formed in a part of the receiving surface 13c of a support yoke 13 made of a sintered alloy, and a groove 13d of a constant depth is formed in a rectangular shape made of an elastic body of resin. It was considered that the thick sheet 17 was fitted and fixed in the groove 13d so that it would protrude from the receiving surface 13c of the support yoke 13 by about 0.2 to 0.5 mm.
Furthermore, as shown in Japanese Utility Model Application No. 57-141256, the base material of the rack guide is made of a metal material such as Al or Fe, and a fluorine-based synthetic resin layer is formed on the entire sliding surface of the base material. Such rack guide devices are known.

生しない。 Next, the effect will be explained. When either the pinion shaft 111 side connected to the handle shaft or the rack shaft 112 side connected to the steering wheel rotates or slides,
Frictional sliding occurs between the back surface 112b of the rack shaft 112 and the surface of the seat 117. The back surface 112b has a coefficient of friction of 0.15 or more when sliding on a sintered alloy (iron-based), and a low coefficient of friction 0.05 to 0.1 when sliding on the surface of the protruding sheet 117, so that both Sliding resistance is greatly reduced due to the difference in friction coefficients. After the protruding coating layer wears out and becomes flush with the support yoke bearing surface 113c, the coating layer and the support yoke bearing surface 113c come into contact with the rack shaft 112 at the same time, and the wear rate as a yoke bearing surface increases. It is possible to significantly reduce the occurrence of backlash and minimize the occurrence of backlash. of course,
The presence of the coating layer effectively reduces the frictional resistance of the support yoke receiving surface, which is the sliding surface of the rack guide. In addition, the rack shaft 11 caused by the meshing of the pinion teeth 111a and the rack teeth 112a
Support yoke 1 due to the component force perpendicular to the axis of 2
13 is pressed in the axial direction, but since the seat 117 is made of a thin steel plate, there is almost no deformation, and the necessary handle rigidity is maintained. In addition, since the seat 117 is difficult to deform, the load of the spring 116 that presses the support yoke 113 can be increased, and the rear end surface 113b of the support yoke 113 and the yoke plug 115
The gap with the tip end surface 115a can be made small and no collision noise is generated.

れた作用、効果を有する。(Effects) According to the present invention, a support yoke that supports the rear surface of the rack shaft is slidably attached to a hole perpendicular to the rack shaft formed in the housing, and a spring presses the rack shaft against the pinion shaft. In the pinion type steering device, the support yoke is formed of a hard material having sliding properties, and has a support yoke main body having a concave receiving surface as a second sliding surface that can come into contact with the rear surface of the rack shaft;
a thin steel plate whose surface is coated with a fluorine-based low friction coefficient resin and whose overall shape conforms to the concave receiving surface of the support yoke body, and a recess provided at a constant depth in the concave receiving surface of the support yoke body; and a sheet as a first sliding surface fixed so that the surface slightly protrudes from the concave receiving surface of the support yoke body and comes into contact with the back surface of the rack shaft, and the sheet has a fixing surface in the center. A convex portion is formed, and the convex portion is fixed to the support yoke body by press-fitting the convex portion into a hole formed deeper than the concave portion in the center of the concave portion of the concave receiving surface of the support yoke body. 1. The protruding coating layer as a sliding surface effectively reduces the frictional resistance of the concave receiving surface as the second sliding surface of the support yoke body, which is the sliding surface of the rack guide, and prevents wear of the protruding coating layer. After becoming flush with the support yoke receiving surface, the coating layer as the first sliding surface and the receiving surface of the yoke body as the second sliding surface come into contact with the rack shaft at the same time, and the yoke body The wear rate of the bearing surface is significantly reduced, and the occurrence of backlash can be kept to a minimum. Of course, the frictional resistance of the receiving surface of the support yoke body, which is the second sliding surface of the rack guide, is effectively reduced by the presence of the coating layer, which is the first sliding surface, and as a result, the rigidity of the support yoke portion is reduced. The sliding resistance between the easy shaft and the support yoke can be reduced, the handle rigidity can be maintained, and the support yoke has good durability under high loads and high temperatures (approximately 120℃), and the easy shaft will not rattle early. It has excellent functions and effects that could not be expected from the first reference, such as being able to eliminate the collision noise between the rear end surface and the front end surface of the yoke plug.

入嵌合部にも過大な応力がかゝることもない。 Further, the sheet is fixed to the main body only by press-fitting the central convex portion into the hole of the main body recess.
This is because both the seat and the main body are made of hard material, so a sufficient fixation can be obtained even by press-fitting, and as mentioned above, the seat is shaped to follow the concave receiving surface of the main body. The load of the rack shaft can be received by the entire surface of the seat corresponding to the sliding surface with the rack shaft, and there is no risk of unbalanced load being applied to the seat, and no excessive stress is applied to the press-fitted portion.
