<p>PROBLEM TO BE SOLVED: To improve the line production efficiency and to allow spot welding generating less distortion by connecting a sheet metal cabin ceiling to right and left sheet metal fenders with a sheet metal pillar, and by connecting the cabin ceiling to right and left steps with the pillar made of either a sheet metal or a steel tube, respectively. SOLUTION: In a cabin 1, a sheet metal cabin ceiling 9 is connected to right and left sheet metal fenders 10 with a sheet metal pillar 11, and the sheet metal cabin ceiling 9 is connected to right and left sheet metal steps 12 with the pillar 13 formed of either a sheet metal or a steel tube. They constitute a skeletal body of the cabin. The right and left steps 12 constitute footplates for an operation and driving machine to which a door 15 is attached with hinge metal fittings 14. This constitution makes it possible to perform the spot welding without generating distortion at each portion and the line production.</p> |
