PROBLEM TO BE SOLVED: To provide a slope structure miniaturized in a simple structure, which can suppress sudden turning of a slope plate and decrease a control force required for turning of the slope plate.SOLUTION: A slope structure of a vehicle 1 comprises: a support plate 4; a slope plate 5; and a hinge 6. A hinge 6 rotatably connects the support plate 4 with the slope plate 5 around a torque rod 21 extending in an open width direction of an entrance in a cabin side of the entrance. The torque rod 21 is twisted according to tilting of the slope plate 5 and energizes the slope plate 5 in a direction opposite to the twisted direction.SELECTED DRAWING: Figure 3
