To provide a lower traveling body which can fix a transformer lifter to an intermediate position without the necessity of processing to the lower traveling body itself.SOLUTION: A lower traveling body of one embodiment of the present invention comprises a pair of crawler units which are arranged while separating from each other in a vehicle width direction, a car body to which the crawler units are detachably attached, and a transformer lifter for lifting the car body. The transformer lifter has an arm attached to the car body so as to be turnable, and a fixing mechanism for fixing the arm obliquely with respect to the vehicle width direction in a plane view, and the fixing mechanism has a penetration hole which penetrates the car body and can expose a side edge of the arm, and a fixing pin inserted into the penetration hole and abutting on the side edge from a sideway.SELECTED DRAWING: Figure 4

    【課題】本発明は、下部走行体自体への加工を必要とせず、トランスリフタを中間位置に固定可能な下部走行体の提供を目的とする。【解決手段】本発明の一態様に係る下部走行体は、車幅方向に離間して配設される一対のクローラユニットと、このクローラユニットが着脱可能に取り付けられるカーボディと、上記カーボディを持ち上げるためのトランスリフタとを備え、上記トランスリフタが、上記カーボディに回動可能に取り付けられるアームと、平面視で上記アームを車幅方向に対して斜めに固定する固定機構とを有しており、上記固定機構が、上記カーボディを貫通し、上記アームの側縁を露出可能な貫通孔と、上記貫通孔に挿入され、かつ上記側縁に側方から当接する固定ピンとを有する。【選択図】図4
