The production method disclosed is a method for producing a front axle beam. The production method includes a die forging step and a bending step. The die forging step is a step of forging a steel material with dies to produce a forged product including a rough web part, which is to be formed into a web part, and four plate-shaped rough flange parts protruding frontward and rearward from an upper side and a lower side of the rough web part, respectively. The bending step is a step of pressing at least one specified rough flange part, which is at least one of the four rough flange parts, with a first die to form a bent portion in the specified rough flange part such that the bent portion is bent inward in an up-down direction of the forged product.

A ridgeline of a bottom surface portion at a rear portion of a rear side member rear at a rear of a fastening portion of rear side members to a rear portion of a rear suspension member is a slope shape which inclines downward toward a vehicle rear. A side member reinforcement, which is a reinforcing member which is against a load in a vehicle length direction, is attached to the rear portion of the rear side member rear. A fragile portion of low rigidity compared to a lower portion is formed at an upper portion of the side member reinforcement.

The present invention relates generally to motorized vehicles and more specifically to a three wheeled motorized vehicle providing a hybrid crossover between an automobile and a motorcycle that is able to take tight corners like a motorcycle by provision of a segment enclosing the operator that can lean into turns, The front segment contains two wheels for both steering and propulsion and is conventionally constructed like any typical front wheel drive vehicle. The rear segment contains the operator (and optionally passenger) supported on a single wheel, The two segments are joined together via a coupling that both supports the assembly and allows rotation of the rear segment about the longitudinal axis to perform the lean for operator and or passenger comfort, while transmitting critical control functions.

A motor drive device includes: a trailing arm that extends in a vehicle front-rear direction and includes a vehicle body-side attachment portion and wheel-side support portion, the vehicle body-side attachment portion formed on a forward portion side of the trailing arm and coupled to a vehicle body via a rubber bush, the wheel-side support portion formed on a rear side of the trailing arm and supporting a rear wheel; and a motor that is supported by the trailing arm and drives the rear wheel. The motor and the rubber bush are disposed in such a way that motor and the rubber bush are seen as being substantially aligned in a vehicle up-down direction when viewed in a vehicle width direction.
