PURPOSE:To lessen vibration of a car body and noise (filling inside) generated by the vibration inside the car by arranging front or back frame members which form an engine room asymmetrical to the longitudinal center line. CONSTITUTION:Left front upper skelton frame 6 is composed of a back frame 6(r) which gradually expands like a fan in its vertical width as well as inclines downwardly to the back, and a frontframe 6(f) which stretches almost straight to the front from the back frame 6(r). Right from upper skelton frame 7 is composed of a back frame 7(r) which gradually expands like a fan in its vertical width as wells stretches almost horizontally to the back, and a front frame 7(f) which stretches almost straight from the back frame 7(r). As stated above, the skelton structure of the front car body B(f) becomes asymmetrical to the longitudinal center line L-L, and bending resonance is hard to happen. As the result, the vibration and the noise can be lessened. |
