1. A jacking point structure disposed to project from a bottom surface of a vehicle and structured to be jacked up by a jacking device, the jacking point structure comprising:
a bottom including:
a jacking point surface structured to be lifted up first by the jacking device; and
a partial contact surface disposed around the jacking point surface, wherein:
the bottom of the jacking point structure includes a recessed portion having an inversed U shape when viewed at a cross section;
the jacking point surface is composed of a bottom surface of the recessed portion;
the partial contact surface is composed of an inclined inner side surface of the recessed portion;
each of the jacking point surface and the partial contact surface is flat;
the bottom of the jacking point structure includes a curved surface between the jacking point surface and the partial contact surface;
the curved surface has a curvature radius set such that the curved surface is approximately flat; and
the partial contact surface is structured such that the jacking device comes out of contact with at least a portion of the jacking point surface and comes into oblique partial contact with the partial contact surface when the vehicle is maximally inclined during jacking-up of the vehicle.
