Abstract: A processing method for a metal plate includes a curve surface forming recess forming step, a protruding step, and a shaping and dividing step. In the curve surface forming recess forming step, a recess is formed in the metal plate, the recess having an outer periphery forming a curve surface, a side portion formed in a frustum, and a bottom portion being round. In the protruding step, a portion of the recess from the bottom portion to the side portion is protruded toward an inside of the recess, and the side portion of the recess is formed to be close to a center of the recess. In the shaping and dividing step, the protruded portion and the outer periphery of the recess are shaped so that the recess is divided into a group of the plural recess portions adjacent to each other.

Abstract: A vehicle charging port arrangement is provided with a vehicle body, a charging port support member and an electric charging port. The vehicle body includes a vehicle front end portion. The charging port support member is supported on the vehicle front end portion. The charging port support member includes an energy absorbing structure that is configured and arranged to deform towards a support structure of the vehicle front end portion and into an energy absorbing area that is disposed forward of the support structure of the vehicle front end portion during a frontal impact. The electric charging port is attached to the charging port support member, with the electric charging port being configured to receive an electric charging connector.

Abstract: A front underfloor structure of a vehicle (EV) includes a protruding member protruding downward from a front underfloor surface of the vehicle, and redirects a flow of traveling air that flows around a front underfloor while traveling. The protruding member is configured as a protruding member with curved surface (31) disposed at a position closer to the vehicle front than front tires (1L, 1R) and in a central portion of the front underfloor straddling a vehicle center line (CL). The protruding member with curved surface (31) has a circumference of protrusion in a vehicle longitudinal direction that is longest at the position of the vehicle center line (CL), and the circumference of protrusion in the vehicle longitudinal direction becomes gradually shorter with increasing distance from the vehicle center line (CL) on both sides in a vehicle width direction.

Abstract: A front underfloor structure of a vehicle includes front deflectors disposed forward of front tires, respectively. The front deflectors each include a front apex portion disposed at a position closer to the vehicle front than a leading edge surface of each of the front tires when straight, and disposed at a position closer to a vehicle center line than an inner surface of each of the front tires when straight; an outer end portion disposed at a position closer to the vehicle rear than the front apex portion, and disposed at a position outward in the vehicle width direction of the front apex portion; and a second flow redirection surface connecting the front apex portion and the outer end portion, and being configured such that, when struck by air traveling from the vehicle front, the second flow redirection surface redirects a flow of the traveling air outward in the vehicle.

Abstract: A drive unit of a hybrid vehicle has an engine and a motor within a drive unit compartment. A side member is disposed on one side within the drive unit compartment, and extends in the longitudinal direction of the vehicle. A side insulator is fixed to the side member and resiliently supports one side of the drive unit. A power unit mounting member is fixed so as to straddle the side member and the side mounting insulator. A power head is mounted on the power head mounting member.

Abstract: A novel automotive front lower structure is disclosed, in which the rear ends of left and right under covers are located symmetrically, so that the hot air in the drive unit mounting room is exhausted equally from the right and left rear ends of the under covers. Also, air spoilers arranged at the rear ends of the under covers improve the effect of negative pressure generation for an improved hot air exhaustion performance.
