帯式車輌の走行装置。[Claims for Utility Model Registration] 1. In a track-type vehicle equipped with a pair of left and right running devices in which an endless track is wound around two roller means, at least one part of the track capable of contacting the ground-contacting side portion of the track from the inside is provided. Two guide means are provided on each of the pair of traveling devices, and selectively configured such that a contact portion of the guide means with the crawler track is located below a contact portion of the roller means with the crawler track. A traveling device for a crawler-type vehicle, characterized in that a displacement generating means for moving the guide means is provided, and the ground contact length of the crawler track can be changed by operating the displacement generating means. 2. The displacement generating means is configured to be interlocked with the larger output of the driving means for rotationally driving one of the roller means of the pair of left and right traveling devices, and the displacement generating means is activated when the traveling direction is changed. 2. The traveling device for a track type vehicle according to claim 1, wherein
