Abstract
A mast structure of a forklift truck is composed of two vertically and parallelly extending channel members each of which has front and rear flanges. The thickness of the rear flange is so larger than that of the front flange that a ratio (e.sub.1 /e.sub.2) of a front-side figure center distance (e.sub.1) between a front-most end of the channel member and a center of figure in cross-section to a rear-side figure center distance (e.sub.2) between a rear-most face of the channel member and the center of figure is within a range of 1.1.ltoreq.e.sub.1 /e.sub.2 .ltoreq.1.5, thereby effectively improving flexural and torsional rigidities of the mast channel member of the forklift truck.
