PURPOSE: To reduce the transmission of vibration into a cabin formation part and improve safety in the collision of a vehicle by devising the rigidity of a frame member or the mass distribution.
CONSTITUTION: The rigidity or mass of the front side part 12F and the rear side part 12R of a frame member 12 on which a suspension installation part is installed is set larger than that of an intermediate part 12M positioned between both the parts, and a cabin formation part 13 of the car body part is formed in separation from the car body front part and rear part. Further, in order to prevent the deformation of the cabin formation part accompanied with the deformation of the intermediate part, a wire 7 for releasing the cabin formation part from the deformation direction in the deformation of the front side part of the frame member is installed in a frame 14.
