• a rear slide rail that is provided on the frame between the front wheel and the rear wheel of the electric powered vehicle over the vehicle width direction and supports a rear end side of the battery;
• a pair of side plate portions that are provided on the left and right ends of the front and rear slide rails, and form an opening that opens in the vehicle width direction between the front and rear slide rails;
• a guide portion that is formed at least on one end side of the opening in the side plate portions, expands the opening in the vehicle front-rear direction and a height direction toward an outside in the vehicle width direction;
• and
• a stopper mechanism that is provided on each of the side plate portions, and restricts movement of the battery inserted during replacement of the battery;
• wherein the stopper mechanism in each of the side plate portions comprises:
• a protrusion that protrudes from the inside of the corresponding side plate portion into the opening and is movable up and down, and has an inclined surface facing the outside of the opening and a stopping surface facing the inside of the opening;
• an elastic member that urges the protrusion upward;
• an elastic member support that holds the elastic member from below;
• a cylinder that moves the elastic member support forward and backward;
• and
