A crawler device 2 is provided with a crawler unit 5. The crawler unit 5 has: a first support 10 extending along a first rotation axis L1; a pair of crawler units 20A, 20B provided to the first support 10; and a pair of grounding mechanisms 30A, 30B provided to the first support 10. The grounding mechanisms 30A, 30B are disposed on the outer side of the crawler units 20A, 20B in the direction facing the crawler units 20A, 20B. The crawler unit 5 is supported by second supports 41, 42 so as to be rotatable around the first rotation axis L1. The outer circumference forming the cylindrical shape of the crawler unit 5 has first zones Z1 occupied by the crawler units 20A, 20B, and second zones Z2 occupied by the grounding mechanisms 30A, 30B, said first zones Z1 and second zones Z2 alternating in the circumferential direction. |
