ABSTRACT:
When an external force acts on a front side of a cab 10 at the time of a car collision or the like, the front side of the cab is deformed, so that a passenger space 15 is reduced from a value C to a value d. On the other hand, a power plant 3 advances because of an inertia force, and an oil pan 2 of the power plant 3 is brought into striking engagement with a suspension cross member 1, and therefore is prevented from further advancing. The value of the distance b between the power plant 3 and a rising portion 16 of a floor panel 14, as well as the value of the distance a between the suspension cross member 1 and the oil pan 2, is suitably determined, and also deforming properties of deformable members of the oil pan 2 are suitably determined. By doing so, the reduction or deformation of the passenger space 15 from the power plant side is prevented, thereby securing the safety of the passengers.
