Abstract

A track frame (11) is composed of a center frame with an upper revolving body attached in position through a barrel (13), right and left side frames (21, 21) positioned on the right and left sides of the center frame (12) and longitudinally extending, and adapted to have caterpillars attached thereto, and front legs (30) and rear legs (31) connecting the side frames (21) to the center frame (12). And, these front and rear legs (30, 31) are formed, for example, of circular hollow pipes, such that the cross-sectional shape of the upper side is inclined. This ensures that even if mud and soil splashed tend to adhere to and accumulate on the front and rear legs (30, 31) and the like, such mud and soil fall along the inclined cross-sectional shape; thus, adhesion and accumulation of mud and soil is prevented.
