A left vehicle width expansion/contraction device (15) enables a rod (16B) of a hydraulic cylinder (16) to extend and contract to move a left side frame (6) in the left-right direction relative to a center frame (5), and a right vehicle width expansion/contraction device enables the right side frame to move in the left-right direction to expand and contract the vehicle width of a lower traveling body (4). The hydraulic cylinders (16) of the left and right vehicle width expansion/contraction devices (15) are positioned between the drive wheels (9) and the guide wheels (10) and are attached to the side frames (6).
左侧的车宽扩缩装置(15)使液压缸(16)的杆(16B)伸长、缩小来使左侧的侧框架(6)相对于中央框架(5)在左右方向上移动,同样,右侧的车宽扩缩装置使右侧的侧框架在左右方向上移动,从而使下部行驶体(4)的车宽扩大、缩小。左右的车宽扩缩装置(15)的液压缸(16)位于驱动轮(9)与引导轮(10)之间并安装于侧框架(6)。
