The crawlers 3 have a plurality of crawler external teeth 3b; a tracker roller 5 that prevents bending in the rotation circumferential direction of the crawler 3; the inside cover 4a and the outside cover 4b that have contours larger than the outside diameter of the wheels 20-23 and have the contours smaller than each of crawler external teeth 3b and cover inside and outside of side surfaces of the wheels 20-23 and inside and outside of between front and rear wheels 20 and 21 and between 22 and 23.
