PORTABLE RAMP
A ramp includes a plate member. The ramp is formed from a carbon fiber-reinforced resin having a longitudinal elastic modulus in the bridging direction of 50+ GPa, and a connecting section that connects the plate member which plate member can be divided into two in a plane perpendicular to the plate member and parallel to the bridging direction. A reinforcement part forms a plurality of hollow segments arranged single file along the bridging direction of the plate member. The cross section shape perpendicular to the direction of extension of the hollow segments is trapezoidal, the height of the trapezoid is 10 to 50 mm, the base angles are 45° to 90°, the width of the plane that contacts the trapezoidal plate member is 100 to 10 mm, and derailment preventing walls connect to portions of plate member side end faces and hollow segment side end faces.
