従来のバイブ材製スタビライザでは、パイプ材の端部の
熱間処理による増肉加工や、中間部分の熱処理のために
その製造に多くの工数を要し、量産性に劣り、勢いコス
トアップとなるという問題があった。(Problems to be Solved by the Invention) Conventional stabilizers made of vibrator materials require a large number of man-hours to manufacture due to thickening processing by hot treatment of the end of the pipe material and heat treatment of the intermediate portion. There was a problem that mass production was poor and costs increased.

てかしめ付けたことを特徴とするものである。[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems of the prior art, the present invention provides an end reinforcement having a wall thickness necessary for welding to the suspension at both ends of the pipe material. It is characterized in that the meat cylinders are fitted together and the fitting portions of both are pressed together and caulked.
（作 用）

持たせることができる。(Function) With the above configuration, the strength of the pipe material does not deteriorate while giving both ends of the pipe material the necessary wall thickness for welding, and the pipe material has sufficient function as a stabilizer. Can be done.
（実施例） 以下、本発明を図面に示す実施例を参照して説明する。(Example) The present invention will be described below with reference to embodiments shown in the drawings.

肉用筒体５，５とからなっている。The stabilizer 3 according to the present invention has an external appearance shown in FIG.
As shown in the figure, there is a pipe material 4 formed to have a wall thickness of about 2 to 3 m/m by cold drawing, for example, and a thickened end portion that is fixed to both ends of the pipe material 4 by caulking. It consists of cylinder bodies 5, 5.

。As shown in an enlarged cross section in Fig. 3, the thickening cylinder 5.5 has a wall thickness t (5 m/
m), and the outer shape is cut to a predetermined size, and approximately half of the inner circumference in the axial direction corresponds to the end 4A of the pipe material 4.
It is formed in a large diameter portion 5A having an inner diameter that can be fitted into the large diameter portion 5A.

になされている。Thickening cylinders 5 are attached to the ends 4Δ and 4A of the pipe material 4.
, 5, and the outer periphery of the thickening cylinder 5 is held by the holder 6 as illustrated in FIG. 4 (△) and <B). The core metal 7 is press-fitted in the direction of the arrow inside 4Δ, and the outer periphery of the end 4A of the pipe material 4 is attached to the thickening cylinder 5.
It is pressed against the inner periphery of the large diameter portion 5△ and is caulked. For this caulking, the outer circumferential surface of the end portion 4A of the pipe material 4 or the inner circumferential surface of the large diameter portion 5Δ of the thickening cylinder 5 is formed by knurling, a group of uneven grooves, or an uneven groove 8 such as a spiral groove. are formed so that they can be more reliably and firmly integrated when caulked.

少なくてすむ。The stabilizer 3 configured as described above is welded to the eggplant pension in the same manner as in the past, but the welding is performed by attaching a thickening cylinder to the end 4A of the pipe material 4 as shown in FIG. Since the suspension arm 1 is welded to the 5 portion, the heat due to welding does not directly reach the pipe material 4, and the strength of the pipe material 4 does not deteriorate. In addition, since the vibrator material 4 itself can be formed by cold drawing and the thickening cylinders 5.5 can be cold-tightened and integrated with the ends 4A, 4A, productivity is high and the number of man-hours is reduced. I'll try it.

ビライザを供給することができる。As explained above, in the automobile stabilizer according to the present invention, end thickening cylinders having a wall thickness necessary for welding to the suspension are fitted to both ends of a pipe material, and the fitting portions of the two are pressed together. Since the structure is crimped and crimped, there is no strength deterioration due to heat unlike in the case of thickening by conventional hot processing, and by using a material formed by cold drawing for the pipe material, work hardening is achieved. Therefore, even a stabilizer made of vibrator material can have sufficient strength. Furthermore, since no hot treatment or heat treatment is required, productivity is excellent, and a lightweight and inexpensive stabilizer can be provided.
