Abstract
An upper rotation body is rotatably attached on a lower travelling body. A storage battery module is loaded onto the upper rotation body. The storage battery module has a plurality of plate-shaped storage battery cells that are stacked in z direction when an xyz rectangular coordinate system is defined. At least one heat transfer plate is arranged between the storage battery cells. Pressing plates, which are arranged at both ends of the stack structure of the storage battery cells, apply a compressive force in the stacking direction to the storage battery cells. A first wall plate and a second wall plate pinch the stacked body in the y-direction and are fixed to the pressing plates. The positions of the heat transfer plates are restricted with respect to the first wall plate and the second wall plate.
