<p>PROBLEM TO BE SOLVED: To provide a crawler type travel device for increasing an expansion-contraction stroke of a crawler, while maintaining even durability of a fitting part between a car body and a crawler frame, by maintaining frame rigidity of the car body.SOLUTION: A crawler frame 20 comprises an overhang part 13 of laterally projecting in front and in rear of a car body main body 11 and a fitting part 22 slidably fitting in the vehicle width direction, and thereby, the crawler frame 20 is movably connected in the vehicle width direction to a car body 10. A root part 14 of the overhang part 13 to the car body main body 11 is inclined so that the distant side from a turning center C of a swivel base 12 on the longitudinal direction in a plan view, becomes near to a central axis CL in the vehicle width direction of the car body main body 11. An outside end part 15 in the vehicle width direction of the overhang part 13 is parallel to the longitudinal direction. An opening end part 23 of the fitting part 22 is inclined as a whole in the same direction as the root part 14 of the corresponding overhang part 13 in a plan view.</p> |
