Title:
STABILIZER MANUFACTURING METHOD, STABILIZER, AND TUBULAR MEMBER FOR MANUFACTURING STABILIZER
Document Type and Number:
WIPO Patent Application WO/2023/120665
Kind Code:
A1
Abstract:
In this method of manufacturing a stabilizer, a tubular member includes: a tubular central part; a first constricted-diameter part that is provided on one end of the central part, that has a thickness equivalent to that of the central part, and that constitutes a tubular form with a smaller diameter than the central part; a second constricted-diameter part that is provided on the other end of the central part, that has a thickness equivalent to that of the central part, and that constitutes a tubular form with a smaller diameter than the central part; a conical first connection part for connecting the central part with the first constricted-diameter part; and a conical second connection part for connecting the central part with the second constricted-diameter part. A pair of first pressing members are used to pinch in and press the first and second constricted-diameter parts of the tubular member, respectively, thereby forming first and second end parts that constitute both ends of the stabilizer and that have a thickness equivalent to that of the stabilizer main body.
