The vehicle has track frames (16) on each of which the semi-track unit (2) is swingably supported with respect to the traveling machine body (3) through the swing shaft (22), drive wheels (11) provided on the drive shafts (26), front side non-driven wheels (12) and rear side non-driven wheels (13) that are arranged such that the horizontal distance between the drive wheel (11) and the front side non-driven wheel (12) is larger than the horizontal distance between the drive wheel (11) and the rear side non-driven wheel (13), and track belts (15) of which each is placed around the drive wheel (11), the front side non-driven wheel (12), and the rear side non-driven wheel (13). The swing shaft (22) is located at a position displaced from a vertical line running through the center of the drive wheel (11).
