ラベルト。[Scope of Claim for Utility Model Registration] (1) Tensile rope and a canvas for protecting the tensile body, which is in contact with the lower surface of the tensile rope, are buried in parallel in the tension part of the belt made of polyurethane elastic material. At the same time, a toothed belt body is formed by providing a group of inverted trapezoidal teeth, also made of a polyurethane elastic material, at a predetermined pitch on the inner circumferential surface of the tensioning part, and a belt width plate also made of a polyurethane elastic material is provided on the back surface of this belt body. A caterpillar belt is made by arranging a group of protrusions extending in the direction at a predetermined pitch, and integrally molding the belt main body made of polyurethane elastic material, the teeth group, and the protrusion group. (2) The group of protrusions arranged on the back side of the belt main body is a band-like body in which the group of protrusions is arranged in a protruding manner at a predetermined pitch on a band-like substrate made of polyurethane elastic material, and the toothed belt is A caterpillar belt according to claim 1, which is integrally molded with a main body. (3) Each component of the caterpillar belt is
The caterpillar belt according to claim 1 or 2, which has been registered as a utility model and has a hardness of 70 to 80 degrees in the protrusion portion and 90 degrees in the tensile portion and the toothed portion. (4) Each component of the caterpillar belt is
The caterpillar belt according to claim 1 or 2, wherein the hardness of the protrusion portion is set to 80°, the tension portion is set to 60°, and the toothed portion is set to 90°.
