A portion where the elastic leg part and the bottom support are connected is closer to a corner than to a center of each side of the bottom support. A right line of a portion of the elastic leg part connected to the bottom support is extended from the bottom support to the upper side in a concave shape with respect to the center of the leaf spring.
