Claims

[Scope of Claim for Utility Model Registration] (1) A part of the left and right wing sections at the boundary between the outer surfaces of a pair of corners facing each other near the center of the core metal is made into a shoulder that is one step higher than the wing section, and the shoulder section includes a wing. An overhang is formed that overhangs forward and backward in the width direction, and the upper surface of the shoulder is configured as an upwardly sloped surface that makes the overhang higher from the vicinity of the center toward the front and rear overhangs. Core metal for rubber crawlers. (2) The shoulder of the core metal for a rubber crawler according to claim (1) has a protruding portion only on one side in the wing width direction, and the protruding portion is formed in opposite directions at the left and right positions,
A core metal for a rubber crawler, characterized in that the upper surface of the shoulder is configured as an upwardly sloped surface that makes the projecting portion higher. (3) The core metal for a rubber crawler according to claim (1) or (2) is buried in a rubber crawler main body so that the upper surface of the shoulder is exposed to the inner peripheral surface of the rubber crawler, and the upper surface of the shoulder is exposed to the outside. A crawler device characterized by a roller track in which the outer rib of a collar-shaped roller comes into contact. (4) A core metal for a rubber crawler according to claim (1), characterized in that the distance between the front and rear protruding portions in the width direction of the right and left wing portions in the shoulders of the core metal for a rubber crawler according to claim (1) is shaped to be one step lower. (5) A core metal for a rubber crawler according to claim (2), characterized in that a region of the core metal for a rubber crawler according to claim (2), excluding an overhanging portion of a shoulder, is shaped to be one step lower. (6) The core metal for a rubber crawler according to claim (4) or (5) is provided within the rubber crawler main body, with the corners of the core metal protruding from the inner circumferential surface of the rubber crawler, and the upper surface of the shoulder step protruding from the inner circumferential surface. A crawler device characterized in that the core metal is buried so as to be exposed in the surface, and the corner top surface and the shoulder top surface of the core metal are used as rolling wheel tracks on which the inner ring and the outer rib of an outer rib type rolling wheel come into contact, respectively. (7) A core for a rubber crawler, characterized in that the left and right corners of the core for a rubber crawler according to claim (2) are shifted to the side opposite to the shoulder on the outside of the corner. Money. (8) The core metal for a rubber crawler according to claim (7) is placed inside the rubber crawler main body, with the corners of the core metal protruding from the inner circumferential surface of the rubber crawler, and the upper surface of the shoulder step being exposed to the inner circumferential surface. A crawler device characterized in that the rubber crawler is buried in such a manner that the respective ends of one corner and the other shoulder of the core bar adjacent in the circumferential direction are slightly overlapped with each other when viewed in the width direction of the rubber crawler. .
