Claims

[Scope of utility model registration request]

In a rubber crawler-type traveling device that supports the weight of the aircraft in contact with the crawler tread protrusions on the outer periphery of the truck rollers attached to the truck frame at predetermined intervals, the The tread protrusion is formed with a notch approximately half its width at the front and rear ends, and the notch on the opposite side of the front and rear ends, so that the tread protrusion has a notch that is approximately half its width in the longitudinal direction of the rubber crawler. A rubber crawler for construction machinery, characterized in that the inner notch and the outer notch of the adjacent tread protrusions are always in a fitted state and are arranged with an appropriate longitudinal gap.
