PROBLEM TO BE SOLVED: To provide an outer frame structure of a crawler capable of preventing a caterpillar to protrude to the outside of a vehicle like a bulldozer when attaching the crawler to the vehicle to run on a snowy road and capable of tightening a nut from the outside like a tire when tightening the nut.SOLUTION: A pipe or rod-like thing 8 is exposed like a frame of a bicycle or a wheel chair to form a triangular shape, thereby, a free space is formed therein. Furthermore, a part for receiving a wheel bolt enters the inside of a caterpillar 3 only in an innermost outer frame 8.SELECTED DRAWING: Figure 5

    【課題】雪道を走るため車にクローラーを取り付ける際にブルドーザーのようにキャタピラが車の外側にはみ出すのを防ぎ、またナットを締める際にタイヤの様に外側から締めることができるクローラーの外枠構造を提供する。【解決手段】パイプ又は棒状のもの8を、自転車や車椅子のフレームの様にむき出しにして三角形状を形成し、内側に空きスペースを作る。さらに一番内側の外枠8の中のみホイールボルトを受ける部分がキャタピラ3の内側に入るようにした。【選択図】図5
