Abstract

PURPOSE:To avoid detaching of a crawler from rotatable wheels by moving the rotatable wheels adjacent to a central rotatable wheel downward by moving quantity smaller than that of the central rotatable wheel interlockingly with the downward moving of the central wheel. CONSTITUTION:In the turn of a crawler 43, a central rotatable wheel 42 is rotated around a fulcrum 17 by the hydraulic operation of a cylinder 44 through a rod 48, links 13, 14 and 12 in the direction of B, and as a result, being pressed, the crawler 43 is readily turned. And for the rotatable wheels 31 and 32 adjacent to the central wheel 42, links 13 and 15 are connected to a rod 48 and link 12 through fulcrums 16 and 18. The distance between the wheel 42 and fulcrum 17 is made to be substantially longer than that from the fulcrum 17 to link 12, the ratio of the distances from the fulcrum 17 of the link 14 to both ends being different from that in the links 13 and 15. Even if the links 13-15 swing by the same angles around the fulcrums 16-18 respectively, therefore, the vertically moving distance of the wheel 42 becomes larger than those of the wheels 31 and 32. This makes it possible to maintain turning performance constant and also to prevent the crawler 43 from detaching from the wheels 31 and 32.
