PROBLEM TO BE SOLVED: To provide a shackle of a leaf spring for a vehicle in which a longitudinal plate member provided with a thick wall part can be manufactured at a relatively low cost as compared with a conventional one.SOLUTION: End parts of a first longitudinal member 18 and a second longitudinal member 20 on a leaf spring side are provided with thick wall parts 18c, 20c which are thicker than a thickness T of parts other than those end parts. The thick wall parts 18c, 20c are formed by press working such that the end parts of the first longitudinal member 18 and the second longitudinal member 20 on the leaf spring side are compressed in a surface direction thereof. Consequently, the thick wall parts 18c, 20c formed on the first longitudinal member 18 and the second longitudinal member 20 are formed not by, for example, welding or casting of a relatively high cost, but by press working of a relatively low cost, and therefore, the first longitudinal member 18 and the second longitudinal member 20, on which the thick wall parts 18c, 20c are formed, can be manufactured at a relatively low cost as compared with a conventional one.SELECTED DRAWING: Figure 2
【課題】肉厚部が形成された長手状板部材を従来に比較して安価に製造することができる車両用リーフスプリングのシャックルを提供する。【解決手段】第1長手状板部材18および第2長手状板部材20のリーフスプリング側の端部には、それらの他の部分の厚みTより厚い肉厚部18c、20cが形成されており、その肉厚部18c、20cは、第1長手状板部材18および第2長手状板部材20のリーフスプリング側の端部を、その端部の面方向に圧縮するプレス加工によって形成される。このため、第1長手状板部材18および第2長手状板部材20に形成された肉厚部18c、20cが製造コストが比較的高い例えば溶接、鋳造によって形成されず製造コストが比較的安いプレス加工によって形成されるので、肉厚部18c、20cが形成された第1長手状板部材18および第2長手状板部材20を従来に比較して安価に製造することができる。【選択図】図2
