ｅｄＰｌａｓｔｉｃ）製のアームが種々提案されている
。(Conventional technology) In recent years, fiber reinforced resin (FRP) has been used to reduce weight while maintaining a certain level of strength.
Various types of arms made of edPlastic have been proposed.
例えば、実開昭６２−７６００９号公報では、フィラメ
ントワインディング成形により製造された繊維強化樹脂
製のサスペンションロアアームか提案されている。For example, Japanese Utility Model Application Publication No. 62-76009 proposes a suspension lower arm made of fiber-reinforced resin manufactured by filament winding molding.
また、特開昭６０−７６４０９号公報ては、表層部に高
強度繊維からなる筒状編組を配置し内層部に短繊維強化
材を用いて圧縮成形により製造されたサスペンションア
ームか提案されている。Furthermore, Japanese Patent Laid-Open No. 60-76409 proposes a suspension arm manufactured by compression molding, with a cylindrical braid made of high-strength fibers arranged in the surface layer and short fiber reinforcement in the inner layer. .
ところて、サスペンションアームなとでは。By the way, it's a suspension arm.
ボールジヨイントなどの継手が接続されているものか多
い。Many have joints such as ball joints connected to them.
この継手の接続は、従来の鉄製またはアルミニウム製な
どの金属製のアームにおいては第３図に示す構造が取ら
れていた。The structure of this joint connection is shown in FIG. 3 in conventional arms made of metal such as iron or aluminum.

ト３の接合力か調整される。This involves forming a hole 2 with a reduced diameter on one side (lower side in the figure) at the end of the arm 1, attaching the lower seat 3 to the inner periphery of this hole 2, and inserting the joint 4 from above the hole 2. However, the upper part of the spherical part 5 of the joint 4 is pressed down by a pressing member 6. The holding member 6 is urged downward by a spring 8 interposed between the cover 7 provided above the hole 2, and the joining force between the spherical part 5 and the lower seat 3 is adjusted by the urging force of the spring 8. be done.
また、カバー７はカバー７か当接している部分のアーム

−５２４１４号に開示されたものなどもある。Further, the cover 7 is fixed by deforming and caulking the portion of the arm 1 (portion A) that is in contact with the cover 7. In addition, as another example of the connection means of the joint 4,
There is also one disclosed in No.-52414.
また、従来の繊維強化樹脂製アームにおける継手の接続

付は孔に継手の球体部を回動自在に支承するソケットを
圧入することにより行なわれている。In addition, to connect a joint in a conventional fiber-reinforced resin arm, a hole is usually formed in the arm in advance, and a socket that rotatably supports the spherical part of the joint is press-fitted into the hole. It is being done.
（発明か解決しようとする課題）

いる。しかし、圧入てはソケットが繊維強化樹脂に強固
に結合されないため、継手に大きな荷重か加わったとき
にソケットが緩んだり外れたりする虞れかあるという問
題点があった。(Problem to be solved by the invention) In this way, when connecting the fiber-reinforced resin arm and the joint, since the fiber-reinforced resin arm hardly undergoes plastic deformation, it cannot be fixed by caulking, and the above-mentioned socket is attached to the hole. Joints are connected by press-fitting. However, press-fitting does not firmly connect the socket to the fiber-reinforced resin, so there is a problem that the socket may come loose or come off when a large load is applied to the joint.
さらに、ソケットとアームとの結合を強固にするために
スナップリング等の固定手段を用いることも考えられる
が、別個に固定手段を用いると作業工程および部品点数
が増えてコスト高となる等の問題点が生じる。Furthermore, it is conceivable to use a fixing means such as a snap ring to strengthen the connection between the socket and the arm, but using a separate fixing means would increase the work process and the number of parts, resulting in higher costs. A point occurs.

きないという問題点もあった。In addition, since only caulking can be performed, it is not possible to create a structure in which the spherical part 5 of the joint 4 is biased by a spring 8 from above to obtain the bonding force between the spherical part 5 and the lower seat 3 as shown in FIG. There was also a problem.
本発明は、以上の問題点に鑑みてなされたもので、その
目的とするところは、継手を強固に接続した繊維強化樹
