摘要： A vehicular suspension arm is provided in which an arm main body (1) includes a main plate (2) press-formed as a main part of the arm main body and having a short cylindrical part (EB) provided integrally with one end by flanging, and a reinforcing plate (H) superimposed on one of upper and lower faces of the main plate (2) and reinforcing the main plate (2). The reinforcing plate (H) has an eye-shaped head part (Ha) formed in an annular shape and arranged coaxially with the short cylindrical part (EB), and a tail part (Hb) extending integrally from the eye-shaped head part (Ha) along the longitudinal direction of the main plate (2), is formed from a single plate material that is thicker than the main plate (2), and has at least the tail part (Hb) welded to the main plate (2). A bush press-fit portion (P1) is formed from an inner peripheral face of the eye-shaped head part (Ha) and an inner peripheral face of the short cylindrical part (EB). This ensures that the cross-sectional shape of a transition section from the bush press-fit portion to the plate-type arm main body is adequate, thus enabling the rigidity and strength required for the transition section to be easily guaranteed and, furthermore, it becomes possible to meet a requirement for increasing the strength of the arm without specially increasing the space around the outer periphery of the bush press-fit portion.
