Stepwise bending in the method for manufacturing a vehicle suspension arm includes a first bending step and a second bending step. In the first bending step, preliminary bending is performed while holding a portion that composes a base portion of a body portion and a portion that composes first coupling portions in a workpiece W by a punch (first punch). In the second bending step, while holding of the portion that composes the first coupling portions by the first punch is released subsequently to the first bending step, bending is performed along a fold given by the first bending step while holding the portion that composes the base portion of the body portion by a punch (second punch).
