This crawler device, which is attached to a tire of a vehicle, is provided with: a frame in which a plurality of rolling wheels are disposed; a crawler which is wound around the plurality of rolling wheels; a movement restriction part for restricting movement of the tire with respect to the crawler device; two rotation-transmission wheels which are attached to the frame so as to be positioned between the tire and the crawler, and which transmit rotation of the tire to the crawler; and a coupling part which has axles of the two rotation-transmission wheels attached thereto, and which is formed from a rod-shaped member capable of having the length thereof set. The frame is provided with a rotation-transmission-wheel movement-enabling part which enables movement of the position of the axle of at least one of the two rotation-transmission wheels in the front and rear directions of the vehicle. The coupling part holds the axles of the two rotation-transmission wheels at a set interval. |
