1. An impact load reduction structure configured to reduce an impact load transmitted to a battery for driving an electrically-powered vehicle, the impact load reduction structure comprising:

  • a crash area that is disposed in a front section of the electrically-powered vehicle and configured to deform at a collision;

    a battery frame that is disposed rearward of the crash area and fixed to a vehicle body frame of the electrically-powered vehicle, the battery frame being configured to support the battery and be engaged with the vehicle body frame in accordance with an inertia force of the collision to be supported from frontward;

    a load reduction frame that extends in a front-rear direction on a front side of the battery frame and that is disposed in a substantially same plane as the battery frame, the load reduction frame having lower rigidity than the battery frame; and

    a load absorber that is disposed between the load reduction frame and the battery frame and that has lower rigidity than the battery frame to deform by being pushed by the load reduction frame and absorb the impact load to be transmitted from the load reduction frame to the battery frame,wherein the load reduction frame extends rearward toward the battery frame from near the crash area and is movable rearward by being pushed after the deformation of the crash area such that the load reduction frame supports the battery frame from frontward via the deformed load absorber.
