No. 485, see Microfilm). In addition, in order to prevent slippage when going up and down stairs, there is known a configuration in which small lug groups for slip prevention are formed between lugs (for example,
JP-A-60-110566).

とになり易くて耐久性がよくないという難点がった。In the former technique described in the prior art, in the former, a spike different from the cored bar is implanted in a spike hole formed in a rubber lug in a plane perpendicular to the flat surface. Therefore, when going up and down stairs, the direction of the spikes is greatly affected by the elastic deformation of the rubber lugs, and the spikes may not function properly, and the external force received by the spikes may be affected by the spikes of the rubber lugs. Repeated local loading of the part has the disadvantage that the part is liable to be damaged early or spikes fall off, resulting in poor durability.

という難点があった。In the latter, a small rubber lug is formed between lugs formed at a predetermined pitch on the outer periphery of a rubber crawler by making the lug lower and narrower than the lugs. Since it was a spike-less type to be installed, there was a drawback that slip prevention at the time of going up and down stairs was lower than that having a spike.

徴とするものである。SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks in the prior art, and has excellent durability while being provided with a spike which functions to prevent slipping when traveling up and down stairs. A rubber crawler is provided. That is, the rubber crawler of the present invention is configured such that a spike is integrally formed on a core bar embedded in the endless band, and the spike is formed in a valley portion between lugs adjacent to each other from the front and rear inclined surfaces of the lugs of the endless band. It is characterized by being protruded toward.

耐久性に優れるものとなった。In the rubber crawler of the present invention, a spike projecting from the front and rear inclined surfaces of the lugs toward the valley between the adjacent lugs always forms at the step corner of the stairs when the stairs are climbed up and down. Since they are involved, the anti-slip function is reliably performed. Since the spikes are formed integrally with the metal core embedded in the endless strip, the spikes do not fall off and the endless strips, especially the lugs, are not damaged early, and the durability is excellent.
