A crawler device includes a wheel support, wheels respectively rotatably supported thereto, and a crawler belt run around the wheels. Each of the wheels includes a rigid wheel body and an elastic material exterior part fixed to an outer periphery of the wheel body. Raised portions are formed in an outer periphery of the exterior part to continuously extend in a width direction and be arranged in a circumferential direction spaced from each other. Drain grooves extending through the exterior part in the width direction are formed between the raised portions. Top surfaces of the raised portions of the exterior part surface contact an inner peripheral surface of the crawler belt with a frictional force working therebetween. Restriction members stopping opposite side edges of the crawler belt are provided in the wheel support to restrict the crawler belt from being displaced with respect to the wheels in the width direction.
