This method for manufacturing a stabilizer forms a first end portion and a second end portion by pressurizing a cylindrical member having a cylindrical central portion, a first diameter-reducing portion, and a second diameter-reducing portion, respectively, by means of a pair of first-group pressurizing members sandwiching the first diameter-reducing portion and the second diameter-reducing portion, the first end portion and the second end portion being formed. A first reduced-diameter section provided on one end side of the central section, having a thickness equal to that of the central section, and having a tubular shape having a diameter smaller than that of the central section; a second reduced diameter section provided on the other end side of the central section, having a wall thickness equal to the wall thickness of the central section, and having a tubular shape having a diameter smaller than that of the central section; a tapered first connecting part connecting the central part and the first reducing part; and a tapered second connection part that connects the central part and the second reduced diameter part, the first end part and the second end part constituting both end parts of the stabilizer and having a wall thickness equal to the wall thickness of the main body part of the stabilizer.

    本发明的稳定器的制造方法是通过利用一对第一组加压部件分别夹住第一缩径部及第二缩径部来对筒状部件进行加压,而形成第一端部及第二端部,其中,所述筒状部件具有:筒状的中央部;第一缩径部,其设置在中央部的一端侧,具有与中央部的壁厚相等的壁厚,呈直径比中央部小的筒状;第二缩径部,其设置在中央部的另一端侧,具有与中央部的壁厚相等的壁厚,呈直径比中央部小的筒状;锥状的第一连接部,其连接中央部与第一缩径部;以及锥状的第二连接部,其连接中央部与第二缩径部,所述第一端部及第二端部构成稳定器的两端部,且具有与稳定器的主体部的壁厚相等的壁厚。
