PROBLEM TO BE SOLVED: To provide a rubber crawler type travel gear suppressing flopping of a rubber crawler by stabilizing a ground contacting state of the rubber crawler with a road surface even when abrupt turning is carried out, suppressing propagation to a vehicular body of vibration due to a fluctuating load acting on the rubber crawler following turning, and improving ride comfort. SOLUTION: In the rubber crawler type travel gear, a drive tumbler 2 and an idler tumbler 3 are attached to both end parts of a truck frame 1, a plurality of lower rollers 4 are attached to a lower part of the truck frame 1, and it travels by rotating the rubber crawler 10A wound between the drive tumbler 2 and the idler tumbler 3 by the drive tumbler 2. The lower rollers 4 are arranged so that a lower roller rolling contact surface 15 of the rubber crawler 10A and the lower rollers 4 are separated a predetermined distance t on plain land.
