Claims

[Scope of Claim for Utility Model Registration] ■ A pair of left and right parts protruding toward the inner circumferential surface of a crawler belt 5 that is rotatably hung over the front drive wheel 2 and the rear driven wheel 4. Protrusion 11.11 to prevent wheels from slipping off
are provided at appropriate intervals in the main rotational direction of the bell, and a plurality of roller groups are arranged in a state where they are in contact with the inner circumferential surface of the ground-contact rotation side belt portion 5A of the crawler belt 5, and In a crawler traveling device in which a tension adjustment mechanism 3 that pivotally supports the driven wheel 4 in a manner that allows the position of the driven wheel 4 to be adjusted and fixed back and forth is disposed inside the driven wheel 4, among the driven wheels,
The wheel 6 located at the frontmost end is formed into an outer wheel whose outer circumferential portion is located on both lateral outer sides of the left and right pair of wheel drop prevention protrusions 11.11, and the other wheels 7 and ...and driven wheel 4
, the outer periphery of which is the left and right derailment prevention protrusion 1'l,
11 pairs of internally rotating wheels that are fitted into each other, and these internally rotating wheels 7 and driven wheels 4.
, the auxiliary external rotary wheels 14, the outer circumferential portion of which is located on the lateral side of the pair of protrusions 11 and 11 for preventing wheel slippage, are positioned alternately inside and outside along the belt rotation direction, and A crawler traveling device characterized in that the driven wheel 4 is provided at an outer side. ■ Utility model registration claim No. 0 in which the auxiliary outer roller 14 is integrally formed with the roller 7 and the driven wheel 4.
The crawler traveling device described in Section 1. (2) The crawler traveling device according to claim 0, wherein the auxiliary outer wheels 14 are constructed from a separate member from the rollers 7 and the driven wheels 4.
