<P>PROBLEM TO BE SOLVED: To provide an elastic crawler vehicle capable of attaining high straight-running capability when an elastic crawler with improved running vibration is installed. Ž<P>SOLUTION: The elastic crawler vehicle 1 is provided with an idler 2 for doubling back the elastic crawler 51 with a core bar 52 embedded at an end on the advancing side and a wheel running on the inner-peripheral side of the elastic crawler. The idler includes a pair of driven portions 21, 21 having a columnar peripheral face-like surface which make each of projecting end faces 55a, 55b in a pair of guide projections 54a, 54b integrated with the core bar bring into contact with. The wheel rolls on each of the pair of projecting end faces and includes a pair of rolling peripheral faces 25, 25 each having the columnar peripheral face-like surface 25, 25. The idler is provided so that virtual planes Ra-Rb, La-Lb pass the center between the pair of rolling peripheral faces 25, 25 and are both more inward or both outward than virtual planes R1-R2, L1-L2 orthogonal to the axial direction of the wheel.
