コストも高くなつていた。 Generally, in the A-type arm of this type of vehicle suspension, two upper and lower press-formed steel plates are joined by arc welding at their outward flanges, but these two steel plates are vertically symmetrical. is not formed. For this reason, in this type of A-type arm, it is necessary to prepare a dedicated one for each left and right arm, and for this reason, press molds are required for the upper and lower, left and right arms, and the arc welding process is separate for the left and right arms. Costs were also getting higher.

もにコストの低減を図ることにある。 The present invention was developed to solve this problem, and its main purpose is to form two upper and lower steel plates into a vertically symmetrical shape in this type of A-type arm, and to weld them together by arc welding from only one direction. By forming the arms into shapes that can be joined to each other, the purpose is to allow the right and left sides of this type of A-shaped arm to be used in common, and to reduce costs.

きる。 In order to achieve such an object, the present invention, in this type of A-type arm, forms both steel plates in a vertically symmetrical shape, and also makes the width of one flange part of these two steel plates wider than the width of the other flange part. Its compositional characteristics lie in its formation. Therefore,
In this invention, even if both steel plates are formed in a vertically symmetrical shape, they can be joined by arc welding only from the narrow flange side of both flanges.
This makes it possible to inexpensively provide an A-type arm that can be used for both the left and right sides by selectively using the upper and lower sides. Further, in such an A-type arm, by checking the presence or absence of a welded portion in the flange portion, it is possible to easily determine whether the arm is applied to the left or right side.

An arm shaft portion 20 is attached to the inner surface of the leg portion 11a of
are fitted as shown in FIG. 4, and the arm shaft portion 20 is arc welded to the inner surface of the first steel plate 11 from the arm shaft portion 20 side. Next, the second steel plate 12 is superimposed on the first steel plate 11, and both flange portions 11c and 12c are arc welded from the second steel plate 12 side. In this case, the flange portion 1 of the first steel plate 11
1c is formed wider than the width of the flange portion 12c of the second steel plate 12, so that the flange portion 12
The outer circumferential edge of c is located a predetermined amount inside the outer circumferential edge of the flange portion 11c, and arc welding can be extremely easily performed from the flange portion 12c. Finally, the arm tube portion 30 is arc welded to the legs 11b, 12b of the joined steel plates 11, 12, thereby completing the manufacture of the A-type arm.

の適用状態を容易に判別することができる。 This A-type arm is attached to the vehicle body frame at an arm shaft section 20 and an arm tube section 30 so as to be rotatable up and down, and the arm main body section 10 supports a shock absorber, a wheel, etc. By the way, in such an A-type arm, both steel plates 11 and 12 are attached to their flange portions 11.
Since they are formed in a vertically symmetrical shape only by making the widths of c and 12c different, if they are reversed vertically, they become horizontally symmetrical, and both the left and right arms can be used in common. In addition, in such an A-type arm, the first
The width of the flange portion 11c of the steel plate 11 is set to the second steel plate 12.
Since the width of the flange part 12c is wider than that of the flange part 12c, arc welding of the flange part 12c to the flange part 11c becomes extremely easy, and together with the commonality of both the left and right arms, the price of this type A-type arm is reduced. In addition, by checking the presence or absence of a welded part in the flange part, it is possible to easily determine whether the welding part is applied to the left or right side.
