Abstract

【課題】 高い牽引力を維持することができ、かつ低コストで損傷し難い弾性クローラを得る。 【解決手段】 ラグ群を次の(a)で定義される複数のメインラグ4と、(b)で定義される複数の補助ラグ5とにより構成する。(a)クローラ本体3の幅方向一端から他端に向かうにしたがって回転方向X後方に傾斜する第一傾斜部4Aと回転方向X前方に傾斜する第二傾斜部4Bとからなり、これら第一傾斜部4Aと第二傾斜部4Bとが幅方向に交互に配置されて、クローラ本体3の両端部間を行き渡るように連続して形成されているメインラグ4、(b)クローラ本体3の両端部間を行き渡らない程度の長さを有しかつ周方向で隣接するメインラグ4間のほぼ中央部に配置された補助ラグ5 【選択図】 図1
PROBLEM TO BE SOLVED: To obtain an elastic crawler which keeps high tractive force, saves cost, and is difficult to be damaged. SOLUTION: The elastic crawler has a lug groups composed of a plurality of main lugs 4 and a plurality of auxiliary lugs 5. The main lug 4 is composed of a first tilting portion 4A tilting backward in a rotating direction X from a first end in a width direction of a crawler main body 3 toward a second end, and a second tilting portion 4B tilting forward in the rotating direction X. The first tilting portions 4A and the second tilting portion 4B are alternately disposed in the width direction, and continuously formed so as to spread over between both end portions of the crawler main body 3. The auxiliary lug 5 has length which does not extend all over between both end portions of the crawler main body 3, and is disposed at a generally center portion between the main lugs 4 adjacent to each other in a circumferential direction.
