The central small diameter portion 11 and a pair of left and right rolling wheel large diameter portions 12 sandwiching the central small diameter portion from both sides are integrally formed. The concave portions 2A are formed on the circumferential surface 11a of the central small diameter portion 11 at intervals corresponding to the core metal pitch L of the rubber track. Also, recesses 2B are formed on the circumferential surfaces 12a of the left and right wheel large-diameter portions 12, 12 at intervals corresponding to the core metal pitch L of the rubber track and at the same positions as the recesses 2A in side view.

Is opposed to the protrusion 5 above the metal core 3 in the rubber track 4 as shown in FIG. Therefore, the central small diameter portion 11
Is a sprocket shape that meshes with the protrusion 5 of the rubber track 4.

The portion A where the core metal 3 does not exist is in contact. When the rubber crawler 4 advances from the position shown in FIG. 2 and the portion B where the core metal 3 is located is at the position of the wheel center axis hanging line Y, the concave portion 2B of the circumferential surface of the wheel large diameter portion 12 It contacts the crawler 4. At the same time, the concave portion 2 </ b> A of the circumferential portion 11 a of the central small diameter portion 11 comes into contact with the protrusion 5 of the rubber track 4. As a result, due to the presence of the recesses 2A and 2B, even in a state where the core metal 3 of the rubber crawler is present, similarly to a state where the core metal 3 is not present, the center position P of the wheel from the ground (the wheel from the ground) The center height H) can be kept constant, and the aircraft moves without vibrating up and down.
