FIG. 1 is a side view showing an embodiment of a leading vehicle structure to which the present invention is applied. In the figure, a honeycomb panel 30, a head part outer plate 40, a cab roof part outer plate 50
Is a main member for forming the leading vehicle structure. The honeycomb panel 30 is made of a brazed aluminum honeycomb panel, and unit panels are arranged in the longitudinal direction of the vehicle body and welded to each other. The honeycomb panel 30 is formed in a curved shape so as to match the sectional shape of the vehicle body in the width direction of the vehicle body. The honeycomb panel 30 is also used for the roof portion in the passenger compartment portion. Therefore, in the passenger compartment portion, the honeycomb panel 30 is entirely formed from the side to the roof. Honeycomb panel 30
The height of the is appropriately divided so as to facilitate the assembly. When the honeycomb panels 30 are joined together, the thick edge materials of the unit panels constituting the honeycomb panel 30 are butted and welded. The dimension of the honeycomb panel 30 in the longitudinal direction of the vehicle body is a length obtained by dividing the entire vehicle body length into several parts. The honeycomb panel 30 and the leading part outer plate 40, and the honeycomb panel 30 and the operator's cab roof part outer plate 50 are joined by welding via joints 10 and 20, respectively. Further, the lower side of the honeycomb panel 30 is joined to the side beam 70 forming the underframe by welding. The joint 10 is formed in an arc shape so as to match the sectional shape of the vehicle body. The joint 20 is arranged along the longitudinal direction of the vehicle body. The front skin 40 and the cab roof skin 50 are welded to the outer surface of the skeleton 60 as in the conventional case.
