。(Problem to be solved by the invention) However, in the conventional vibrator stabilizer, the pipe material 3
It is not easy to increase the thickness by hot treatment of the end portion of the pipe material 3, and the intermediate portion 5 must be heat treated, which requires a large number of man-hours for manufacturing, which is poor in mass production. As the length is shortened, the amount of materials used increases, resulting in an increase in costs.
本発明はこれに鑑み、上記従来技術の問題点を解決する

ようにしたことを特徴とするものである。(Means for Solving the Problems) In order to solve the problems of the prior art described above, the present invention expands the diameter of both ends of a pipe material to form a large diameter end. This is characterized in that the base of the suspension is fitted and welded to the outer periphery.

持たせることができる。(Function) With the above configuration, the diameter of the end of the pipe material can be expanded cold, and the section modulus of the large diameter end increases, allowing for sufficient installation without the need for thickening. Strength is obtained, which prevents material deterioration and material waste, and allows the pipe material to have a sufficient function as a stabilizer.
（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.

ている。この大径端部１２．１２の外径りは、パイプ材
１１の外径ｄが２５ｍｍである場合、３０關前後とされ
る。The stabilizer 10 according to the present invention is constructed by cold-drawing both ends of a pipe material 11 formed to a thickness of about 2 to 3 mm by cold drawing, as shown in FIG. 1 and the cross section of both ends in FIG. The large diameter end portion 12.12 is formed by expanding the diameter. When the outer diameter d of the pipe material 11 is 25 mm, the outer diameter of the large diameter end portion 12.12 is about 30 mm.
いま、パイプ材１１の肉厚Ｔを２．５鰭、外径ｄを２５
