C8 Problem to be Solved by the Invention However, in the front structure of the above-mentioned cab-over type vehicle, since the front panel 101 is a single outer plate, the window member 106 is attached to the front panel 101.
Welding the lower edge 106b of the lower end edge 106b of the lower end edge 106b could not be carried out because the welding mark would be visible on the outside, and at most the lower end edge 106b was fixed with adhesive. Therefore, there was a problem in that the strength near the bottom of the window glass 110 was unstable.

Furthermore, since the front panel 101 is a single panel, wind noise and transmitted sound are large during high-speed driving, resulting in a decrease in the temperature inside the vehicle in cold regions.

Furthermore, since it is necessary to install a steering shaft, pedals, heater, air conditioner, etc. on the interior side of the front panel 101, the shape of the front panel 101 cannot be changed freely, and the design of the front part of the vehicle body is free. There was also the issue of low levels.

The present invention has been made in view of the above-mentioned problems with the front structure of conventional cab-over type vehicles.

d. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention forms inner panels constituting front pillars on both left and right sides of a vehicle body from left and right sides of the front panel, and The upper and lower edges of a window member having a substantially U-shaped cross section extending in the width direction of the vehicle are fixed to the upper front surface of the window member, and the left and right edges of the window member are fixed to the front pillar. The front structure of a cab-over type vehicle is such that the upper end of the exterior panel covering the front of the front panel is fixed, and the lower end thereof is fixed to the front panel at least below the upper end of the front bumper.

e. Function In the front structure of the cab-over type vehicle according to the present invention, the inner panel constituting the front pillar is formed on both left and right sides of the front panel as described above, so that the number of parts can be reduced and the structure is waterproof. This reduces the number of panel joints that pose problems, and improves both ease of assembly and waterproofness.

In addition, the wind member, which has a roughly U-shaped cross section and is installed at the front of the upper part of the front panel, has a completely closed section with its upper, lower, left, and right edges fixed to the front panel and front pillar, respectively, resulting in improved rigidity. However, the strength near the bottom of the windshield is sufficient.

Furthermore, in the present invention, the upper end of the exterior panel covering the front of the front panel is fixed to the front surface of the window member, and the lower end thereof is fixed to the front panel below at least the upper end of the front bumper, so that the shape of the exterior panel By changing this, the exterior shape of the vehicle body can be freely designed, and the front of the vehicle body has a double structure consisting of the front panel and exterior panel, reducing wind noise and transmitted sound, and making it easier to use in cold regions. It is possible to prevent a drop in room temperature.
