PURPOSE:To facilitate fitting of sub-caterpillars in a crawler for traveling agricultural machine by fitting a sub-caterpillar at the outside edge of an elastic caterpillar by means of penetration of a set bolt within two caterpillar cores in such a way that the grounding surface is higher than the grounding surface of the elastic caterpillar. CONSTITUTION:The inner edge of a sub-caterpillar b is fitted with the outer edge of elastic caterpillar b by fitting a protrusion 30a of a core metal 30 in a through hole 20a formed in the outer edge of said elastic caterpillar b. A set bolt 40 is inserted in insertion holes y, w in core metals 30, 22 of the two caterpillars a, b and fastened with a nut 40. At this time, the grounding surface of the sub-caterpillar b shall be higher than the grounding surface of the elastic caterpillar a by a specified height H. This accomplishes easy and sure fitting/ removal of sub-caterpillar to lead to prevention of drop of the revolution performance.
