In a suspension arm disposed in the vicinity of a drive shaft, interference with the drive shaft is prevented when an arm body is deformed by load. Between a curved portion (26) of the arm body (14) and a wheel-side mount portion (16), a soft portion (28) is disposed. Thus, upon application of excessive load, the soft portion (28) is preferentially deformed, whereby interference of a lower end portion (26r) with a drive shaft (12) due to deformation of the curved portion (26) can be prevented. Namely, when the strength of the arm body (14) is substantially uniform, bending buckling may develop in the curved portion (26) which is subject to stress concentration because of the curved shape, whereby the lower end portion (26r) may interfere with the drive shaft (12) and be damaged. |
