Abstract

PURPOSE: To provide the subject structure wherein the abutment part of a curvature shape of a ramp main body comes into abutment with the receiving part of a flap forming a plane, and further the flap is fitted to the ramp main body by a double hinge, whereby the hinge is protected and the stability thereof is increased.
CONSTITUTION: An abutting part 6 formed into a curvature shape abutting with a receiving part 7 formed in the width direction at the upper part of the rear end of the flap 4 is provided in the width direction at the lower part of the tip of the ramp main body 3. Further, the intermediate part of the hinge 5 is fitted to the rear end side of the ramp main body 3 from the abutment part 6, and the tip of the hinge 5 is fitted to the rear end of the flap 4, and the rear end of the hinge 5 to an auxiliary cylinder 8 in a rotatable manner. By this procedure, a load applied on the ramp main body 3 is constantly applied on the flap 4 through the abutting part 1 and is not directly applied on the hinge 5. Even when the ramp main body 3 slightly moves vertically and longitudinally, the flap 4 does not move nor its position deviates nor floats up.
