熱歪の除去のためのコストも無視できない。However, the bracket 1 as shown in FIGS. 6 and 7 is made of a steel plate so that the weight can be reduced.
Since the number of component parts is large, it takes time to manage parts,
In particular, the cylindrical boss 4 into which the bush 7 is press-fitted needs to have a strict inner diameter tolerance in order to secure the holding force of the bush 7, which requires a large number of man-hours and is a major factor in cost increase. Had become. Further conventional bracket 1
Therefore, as described above, since there are many welding locations, not only is it troublesome, but also the effect of thermal distortion due to welding cannot be avoided, and the cost for removing this thermal distortion cannot be ignored.

とができる効果がある。According to the bracket of the present invention, a symmetrical shaft support portion is integrally formed with a single plate material with the connecting portion interposed therebetween, and a mounting portion is provided above one of the shaft support portions. Since the connecting portions are integrally formed on the other upper side, and the boundary between the connecting portion and the adjacent portion of the connecting portion is bent inward, so that the left and right shaft support portions are configured to face each other. The component management cost can be reduced by using a single plate material, and the manufacturing cost can be reduced by bending and manufacturing a single plate material, which increases the weight and strength, and hardly requires welding. Has an effect that can be kept low.
