2. Description of the Related Art Conventionally, stabilizers have been provided in automobiles and the like in order to suppress the roll of the vehicle body. As shown in Japanese Utility Model Application No. 58-54308, for example, a conventional stabilizer has both ends connected to a swing arm that can swing the left and right steering wheels independently, and its roll bar section is rotatably supported by the chassis. In such a conventional stabilizer mounting structure, the only problem is that the stabilizer effectively exhibits the originally required anti-roll effect. By the way, the steering gear case of the steering device that steers the steering wheels is attached to the chassis via a mounting bracket, and it is known that the strength of this mounting bracket can affect the steering characteristics of the vehicle. There is. In other words, if the strength of this mounting bracket is insufficient, the lateral force applied to the wheels during steering will be transmitted to the steering gear case, and the steering gear case will be displaced, causing the angle to exceed the actual amount of steering operation. An oversteer phenomenon occurs in which the wheels move to an angle that corresponds to the amount of actual steering operation, and an understeer phenomenon occurs in which the wheels do not move to an angle that corresponds to the amount of actual steering operation. He is known to be unsteady. Therefore, it is desirable that the mounting bracket for the steering gear case to the vehicle body be made as highly rigid as possible. However, in order to meet modern social demands such as energy conservation, it has become important to reduce the weight of vehicle bodies.
In response to the demand for lighter vehicle bodies, it is desired that the mounting bracket be made as thin as possible to reduce its weight. In order to meet this demand for weight reduction, it is not acceptable to make the mounting bracket unnecessarily high in rigidity, and the reality is that the demand for increased rigidity to a certain extent has to be sacrificed. be.

When the stabilizer is connected to the above mounting bracket, the external force applied to one mounting bracket is not only shared to the other mounting bracket via the torsion bar portion of the stabilizer, but also the two mounting brackets are connected to the chassis. A Japanese-shaped structure is formed in which the part, steering gear case, and torsion bar part of the stabilizer are connected, and the two conventional mounting brackets are connected by a part of the chassis and the steering gear case. A much more rigid structure can be obtained compared to the square-shaped structure. Therefore, it becomes possible to reduce the rigidity of the mounting bracket, and it becomes possible to reduce the thickness and weight of the members of the mounting bracket. In addition, since the mounting bracket is reinforced by the stabilizer in this way, the steering gear case is prevented from being damaged by lateral forces acting on the tires.
This prevents displacement of the steering wheel, provides stable steering characteristics with no oversteer, understeer, or lateral vibration while driving straight, and improves the steering feel. Of course, the above mounting bracket is attached to the steering gear case.
Since it is used both for mounting the stabilizer and for mounting the stabilizer, the conventional bracket exclusively for mounting the stabilizer can be omitted, and from this point of view as well, the weight of the vehicle body can be reduced, the number of parts is small, and costs can be reduced. As explained above, according to the present invention, conventionally,
Stabilizers, which were previously used solely to suppress roll, were also used to reinforce the mounting bracket for attaching the steering gear case, meeting the modern demands of ensuring good steering characteristics and reducing the weight of the car body. It is possible to harmoniously satisfy the following.

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view of one embodiment of the present invention, in which 1 is a chassis showing only the parts necessary for explaining the present invention, 2 is a pair of mounting brackets,
3 is a steering gear case, 4, 4 are each tie rod, 5, 5 are each knuckles, 6, 6 are each steering wheels, 7, 7 are each swing arms, and 8 is a stabilizer. The mounting bracket 2 is welded to the horizontal frame portion of the chassis 1 behind the wheels at appropriate intervals in the left-right direction, and the steering gear case 3 is attached to the mounting bracket in front of the mounting bracket 2, as shown in FIGS. 2a and 2b. 10
The torsion bar portion 9 of the stabilizer 8 is attached to the lower surface of the stabilizer 8 using a mounting bracket 11. Note that both ends of the stabilizer 8 are articulated to swing arms 7, 7 that support the steered wheels 6, 6 via knuckles 5, 5, respectively. In this way, when the stabilizer 8 is coupled to the pair of mounting brackets 2, 2, the external force applied to one of the mounting brackets 2 is simply applied to the stabilizer 8.
Not only is it shared with the other mounting bracket 2 via the torsion bar portion 9 of the two mounting brackets 2, but also the torsion bar portion of the steering gear case 3 and stabilizer 8 is shared between the two mounting brackets 2, 2, and a part of the chassis 1, the steering gear case 3, and the torsion bar portion of the stabilizer 8. 9 is connected with the steering gear case 3, and compared to the conventional square-shaped structure in which the two mounting brackets 2, 2 are connected with a part of the chassis 1 and the steering gear case 3. A significantly more rigid structure can be obtained. Therefore, it becomes possible to reduce the rigidity of the mounting brackets 2, 2, and it becomes possible to reduce the thickness and weight of the members of the mounting brackets 2, 2. Furthermore, since the mounting brackets 2, 2 are reinforced by the stabilizer 8 in this way, displacement of the steering gear case 3 due to lateral forces acting on the running wheels 6, 6 can be more reliably prevented than before. , oversteer, understeer, and lateral vibration while traveling straight due to displacement of the steering gear case 3 to which lateral force is transmitted are eliminated. Of course, the above mounting brackets 2, 2 are used for mounting the steering gear case 3 and the stabilizer 8.
Since it is also used for mounting the stabilizer, the conventional bracket (not shown) dedicated to mounting the stabilizer can be omitted, and from this point of view as well, the weight of the vehicle body can be reduced, and the number of parts can be reduced, resulting in cost reduction. Of course, the present invention is not limited to the above embodiment, and the steering gear case 3 and stabilizer 8 may be mounted vertically side by side on the front surface of the mounting bracket 2, as shown in FIGS. 3a and 3b. good. In this case, the mounting bracket for attaching the steering gear case 3 and the mounting bracket for attaching the stabilizer 8 may be formed separately; It is attached to mounting bracket 2.
