NOVELTY - The hanger (10A) has an opening-and-closing arm (24) that is pivotally supported by a main frame (12A) centering on rotational axis by a fixed arm (22) fixed to one end of main frame towards grip position of rectangular parallelepiped battery module and other end of main frame, so that rotation is possible. A control lever (38) is extended upwards, so that the control lever is located in the main frame side and rotates the opening-and-closing arm. A locking mechanism is arranged for fixing the control lever to non-gripping position and grip position with respect to battery module.    USE - Hanger e.g. battery hanger for installing battery modules attached to battery case mounted in electric vehicle.    ADVANTAGE - Since fixed arm and opening-and-closing arm are provided in the ends of main frame, the opening-and-closing arm is operated by the control lever and the rectangular parallelepiped battery module can be gripped effectively by the hanger, so that clamp operation can be performed easily. Narrow space is provided in the opening-and-closing arm in non-clamping position and clamp position of rectangular parallelepiped battery module for clamping the rectangular parallelepiped battery module easily in short time and to lift the rectangular parallelepiped battery module efficiently. Since the control lever exists in the side upper direction of main frame, the control lever can be operated easily regardless of the space between rectangular parallelepiped battery modules. The hanger is simple in structure, so that the manufacturing cost of the hanger can be reduced. By fitting control lever to groove, the opening-and-closing arm can be stably maintained in open position and grip position with respect to rectangular parallelepiped battery module. Hanger is provided in the upper portion of the main frame to easily lift the battery module. Hence, the need for the worker to edit between battery modules can be avoided.
