Since a and 5b have a rib structure as shown in FIG. 8, the distribution of the load in the vertical direction is insufficient, and the load is concentrated on the front center of the bracket. Therefore, reinforcement of the front side is required. Furthermore, since the contribution to torsional rigidity is low, the entire wall needs to be thick, which has the disadvantage of increasing the weight of the entire bracket.

The structure of the present invention to achieve the above object is that the trunnion bracket is composed of a mounting flange section, a torque rod mounting section provided with a shaft mounting hole, and a funnel-shaped wall section provided therebetween.
Shell-shaped space depressions each having a predetermined size and having a wide vertical and horizontal width are provided at both ends of the funnel-shaped wall surface in the longitudinal direction of the vehicle.

With the above configuration, the load in the vertical direction is absorbed by the shell-shaped space recesses, which are made up of spaces of a predetermined size with wide vertical and horizontal widths, provided at both ends of the funnel-shaped wall surface portion in the longitudinal direction of the vehicle. They can be distributed at the front and rear ends of the wall section and at the center of the bracket. Therefore, the section modulus of the bracket is increased and the torsional stiffness is significantly increased. Furthermore, the bracket can be formed with a thin wall, making it possible to reduce the weight of the entire bracket. Further, since the inside of the wall portion is widely opened upward, castability is also improved.
以下、図面に基づき本考案を詳細に説明する。 Hereinafter, the present invention will be explained in detail based on the drawings.

ラニオンブラケツトになつている。 Reference numeral 1 denotes a mounting flange portion that is attached to the side rail and has a substantially trapezoidal shape. Reference numeral 2 denotes a torque rod attachment portion to which a trunnion shaft is attached, and a shaft attachment hole 3 is provided therein. A funnel-shaped wall portion 4 is provided between the mounting flange portion 1 and the torque rod mounting portion 2,
These mounting flange part 1 and torque rod mounting part 2
and the funnel-shaped wall portion 4 are integrally formed by casting. The front and rear ends 5a of the funnel-shaped wall portion 4,
As shown in FIGS. 2 to 4, 5b is a trunnion bracket provided with shell-shaped space recesses 6a and 6b that are triangular spaces with wide vertical and horizontal widths and a predetermined size. .

捩れ剛性が大幅に増大できる。 According to the trunnion bracket having such a structure,
Shell-shaped space recesses 6a and 6b formed of spaces of a predetermined size with wide vertical and horizontal widths provided at the front and rear ends 5a and 5b of the funnel-shaped wall section 4 absorb vertical loads of the wall section 4. It can be distributed over the front and rear ends 5a, 5b and the center of the bracket, and the section modulus can also be increased. Therefore, the bracket can be made of a thin material, and the weight of the entire bracket can be reduced. In addition, the shell-shaped space recesses 6a and 6b provided at the front and rear ends 5a and 5b allow the front and rear ends of the bracket 5
This means that a and 5b are provided with hollow blocks, so to speak, and the section modulus is increased, so that the torsional rigidity can be greatly increased.
加えて、壁面部４の内面が上方方向に広く開口
することになるため、鋳抜き性がよくなる。 In addition, since the inner surface of the wall portion 4 is wide open in the upward direction, castability is improved.
第５図及び第６図は、シエル状の空間窪み部の
