る。By the way, in order to increase the ventilation and ventilation volume of the air duct disposed inside the front panel, it is necessary to make the cross-sectional shape as large as possible, but the cross-sectional shape is simply made large. However, there is a problem in that the air duct also protrudes toward the driver's seat inside the front panel, thereby narrowing the effective space of the vehicle compartment.

It is possible to increase the section modulus of the air duct 4 without narrowing it, and with the increase of the section modulus of the duct 4, not only the strength of the air duct 4 can be increased but also the ventilation ventilation volume can be increased. Since the front wall 52 and the extension wall 8 formed integrally with the air duct 4 which are arranged close to each other are fixed to the inner surface of the front panel 3, respectively, not only the rigidity of the air duct 4 but also the surface rigidity of the front panel 3 can be increased at the same time. Can be done.

While the rigidity of the air duct 4 can be increased, the section modulus of the air duct 4 can be increased and the ventilation volume can be increased without narrowing the effective space in the vehicle compartment located on the rear side of the air duct 4. . Moreover, since the wall portion of the bulging portion 53 is fixed to the front panel 3 and the extension wall 8 formed integrally with the front duct member 5a is also fixed to the front panel 3, only the rigidity of the air duct 4 is increased. Of course, the surface rigidity of the front panel 3 can be increased at the same time.
