Abstract
A vehicular L-type suspension arm is provided in which a wheel support part is provided on one end part of an arm main body, and a first vehicle body side linking portion and a second vehicle body side linking portion are provided in an intermediate part and on the other end part thereof respectively, wherein an arm main body (A) includes an upper half body (AU) that is formed so as to have an inverted U-shaped cross-section and a lower half body (AL) that is formed by press forming a plate material in a shape that blocks the lower open end of the upper half body (AU) and is welded by welds (w) to inner faces of a pair of side wall partsof the upper half body (AU), at the other end part of the arm main body (A) the lower half body (AL) extends lengthwise further outward than the upper half body (AU), an upwardly facing cylindrical bush support part (P) is formed by burring integrally with the extended part (Ale) so that it is the second vehicle body side connecting portion (AF), and an outer peripheral face, close to the intermediate part of the arm main body (A), of the bush support part (P) is butt-welded to an outer end face of the upper half body (AU). Thus, the second vehicle body side connecting portion can be formed by a simple structure in which an extended part of a lower half body of the arm main body is merely subjected to burring.
