ABSTRACT:
A shell structure adapted to accommodate a propelling power unit forms part of a vehicle frame. It is made of a thin sheet, and has no practical strength but is sufficiently reinforced with its opposite side sections firmly secured to the adjacent sides of the power unit. An air path is defined in the shell structure at least between the bottom section thereof and the power unit and, extending between an air inlet and an air outlet opening formed respectively in the front and rear faces of the shell structure, is utilizable to accommodate an exhaust duct. Use of such shell structure enables substantial reduction in vehicle weight and particularly simplifies assembling and maintenance operations of the vehicle.
