さくすると強度が低下するため、補強板を設けることに
よって強度の低下を補うようにしている。(Prior Art) In front-wheel drive vehicles, weight reduction of the front lower suspension arm is being promoted. Therefore, the thickness of the suspension arm is being reduced. However, if the thickness is reduced, the strength is reduced. Therefore, a reinforcing plate is provided to compensate for the decrease in strength.

われている。However, in the structure in which the outer peripheral surfaces of the reinforcing plates a and b are arranged along the inner peripheral surfaces of the suspension arms c and d as described above, the torsional and bending rigidity does not increase so much, and as shown in FIG. In general, the bottom surfaces of a and b are opposed to the bottom surfaces of suspension arms c and d to form a box shape.

て困難であった。(Problems to be Solved by the Invention) In the conventional example as described above, the suspension arms c and d are used.
Since the reinforcing plate is positioned with respect to the inner surface of the suspension arms c and d only in the horizontal direction, and not in the height direction, the reinforcing plates a and b are required to be located at the correct positions. It was extremely difficult to weld to.

て取付けられる。(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a front lower suspension arm, which is bent in a direction perpendicular to a bottom surface 1a and the bottom surface 1a. It consists of a side 1b. Reference numeral 2 denotes a reinforcing plate, which is provided to reinforce the suspension arm 1. The reinforcing plate 2 is attached by welding at a position effective for increasing the strength of the suspension arm 1.

る。First, the position of the positioning pin 3 is set to a position corresponding to both ends of the reinforcing plate 2 when the reinforcing plate 2 is elongated as shown in FIG. As the structure of the positioning pin 3, one having a structure shown in FIG. 2 is used, and the other one having a structure shown in FIGS. 3 and 4 is used. In the case of FIG. 2, the positioning pin 3 is projectingly provided on the bottom surface of the suspension arm 1, and the tip end of the pin 3 is reduced in diameter to form a shoulder 3a, and the shoulder 3a is formed on the shoulder 3a. The end 9c of the shaft 9 is locked. In the case of FIGS. 3 and 4, the positioning pin 3 is projected from the clamp member (not shown) provided on the suspension arm 1 and the spring member 4 is attached.

る。The bent portion 5 is formed by bending a part of one end of the reinforcing plate 2 toward the bottom surface of the suspension arm 1.
さらに、補強板２の両端部には、前記位置決めピン３が
貫通自在な通し孔６が形成されている。Further, through holes 6 through which the positioning pins 3 can freely pass are formed at both ends of the reinforcing plate 2.

決めピン３の長手方向に通し孔６を一致させる。Next, the case of positioning the reinforcing plate 2 will be described. First, the positioning pin 3 of FIG. 2 is inserted into the through hole 6 formed in the one end A of the reinforcing plate 2 to position the one end A. The end 9c of the shaft 9, which is locked on the shoulder 3a of the pin 3, is brought into contact. Then, the lower end surface of the bent portion 5 of the reinforcing plate 2 is brought into contact with the bottom surface of the suspension arm 1, and then the clamp member is pushed down, so that the tip end portion of the spring member 4 comes into contact with the upper surface of the reinforcing plate 2 and the positioning pin. The tip of 3 penetrates through hole 6. When the position of the reinforcing plate 2 is incorrect, the positioning pin 3 does not penetrate the through hole 6, but in this case, the position of the reinforcing plate 2 is moved and the positioning pin 3 is inserted in the longitudinal direction. The holes 6 are aligned.
つまり、補強板２の水平方向の位置は、位置決めピン
３，３によって決定され、高さ方向の位置は、位置決め
ピン３の肩部3aと折曲部５とによって決定される。That is, the horizontal position of the reinforcing plate 2 is determined by the positioning pins 3 and 3, and the height position thereof is determined by the shoulder portion 3a and the bent portion 5 of the positioning pin 3.

る。FIG. 5 shows the case where the reinforcing plates having different shapes from those in FIG. 1 are used. The structure of the positioning pin 3 which can be fitted into the through hole 6 formed at the one end A of the reinforcing plate is shown in FIG. , Second
The structure of the positioning pin 3 which is similar to the drawing and which can be fitted into the through hole 6 formed in the other end B of the reinforcing plate 7 is also the same as that of FIG. 2 as shown in FIG. Since the other end B of the plate 7 only abuts on the shoulder 3a of the positioning pin 3, the holding of the reinforcing plate 7 becomes unstable. Therefore, a part of the one end C between the both ends of the reinforcing plate 7 is bent toward the bottom surface of the suspension arm 1 to form a bent portion 8.
つぎに、補強板７を位置決めする場合について述べる
と、補強板７の両端部における通し孔６のそれぞれに位
置決めピン３，３を挿通させると、補強板７は、両位置
決めピン３の肩部3aおよび折曲部８の３点によって支持

の高さ方向の位置決めは、位置決めピン３の肩部3aと折
曲部８とによって決定される。Next, the case of positioning the reinforcing plate 7 will be described. When the positioning pins 3 and 3 are inserted into the through holes 6 at both end portions of the reinforcing plate 7, the reinforcing plate 7 becomes a shoulder 3a of both positioning pins 3. And the bent portion 8 supports the reinforcing plate 7 while being stably held.
The positioning in the height direction is determined by the shoulder 3a of the positioning pin 3 and the bent portion 8.
このようにして、補強板２，７の位置決めが完了したな
らば、第１図および第５図の斜線部Ｘを溶接する。When the positioning of the reinforcing plates 2 and 7 is completed in this way, the shaded portions X in FIGS. 1 and 5 are welded.
（発明の効果） 本発明は、以上から明らかなように、補強板の高さ方向
の位置決めを、補強板に形成した折曲部を利用して行う
