PURPOSE:To lower the weight of the titled crawler by providing a number of outside projections which are brought into contact with a road face on the outside of an annular belt which is formed into an endless annular shape, providing an inside projection on the center part in the width direction of the inside of the belt, and rotating the belt with the inside projection being interposed between double wheel tires. CONSTITUTION:An annular belt 3 of an elastic material is formed in an endless annular shape on the intermediate layer of an elastic crawler 1 and a number of outside projections 5 of an elastic material are provided on its outside forming a ground contacting face. And, an inside projection 7 of an elastic material is provided continuously in the longitudinal direction in the center part in the width direction inside the annular belt 3. The elastic crawler 1 is put around double wheels in front and in rear of a vehicle. The double wheels are formed with two wheels 10, 11 of an elastic material leaving a space to each other and the inside projection 7 of the annular belt 3 is interposed in the space. As the double wheels are driven, the annular belt 3 is rotated by the frictional force between the inside projection 7 and wheels which elastically hold it in between, without coming off of the wheels.
