Ramp and vehicle ramp device

A ramp, comprising:

• a ramp body having a ramp face and a back face opposite the ramp face;
• support members that are provided on the back face, and that, when the ramp body is used, are each disposed at a respective width direction end of the ramp body so as to run along an extension direction of the ramp body including at an extension direction central portion of the ramp body, the width direction being orthogonal to the extension direction of the ramp body, the support members respectively forming triangular shapes having heights that decrease on progression from one end portion side to another end portion side in the extension direction of the ramp body in side view, and a lower end of each of the support members making contact with a ground contact surface so as to support the ramp body from a back face side;
• a first fold line that is provided at the ramp body, the first fold line being provided running along the width direction of the ramp body, and the first fold line being a point about which the ramp body folds so as to compress in the extension direction;
• and
• a second fold line that is provided at the support members at a different position in the plate thickness direction of the ramp body from the first fold line, the second fold line being a point about which the support members fold to a width direction inner side of the ramp body.
