Therefore, the number of the lifting and lowering modules 130 to be installed for individually adjusting the angle of each unit swash plate 121 can be minimized, thereby greatly reducing the manufacturing cost.

A supporting plate 122 made of a high strength and wear resistant material is mounted on the unit swash plate 121 so that the pressing rod 131 of the elevating module 130 is in contact with the unit swash plate 121, It is possible to prevent the wedge member 121 from being worn or deformed.

When the unit swash plate 121 is formed into a triangular shape or a fan shape, the three elevation modules 130 are disposed at the lower edge of the central side edge A (see FIG. 3) So as to individually press the lower portion of the stage (B).

Therefore, even if any one of the elevating and lowering modules 130 is elevated lower or higher than the set height, the inclination angle of the unit swash plate 121 is inclined toward the elevation module 130 having a relatively lower height, 130, it is possible to effectively prevent the up-and-down flow caused by the clearance D due to the error between the set height and the actual elevated height.

3 and 4, the plurality of lifting and lowering modules 130 are installed on a lower portion of the fixed frame 110 opposite to the center C of the swash plate portion 120, A single central lift module 130a for simultaneously pressing a lower portion of the center side edge A of the swash plate 121 and a lower edge of the boundary position of the two unit swash plates 121 disposed adjacent to each other on the fixed frame 110 And a plurality of outer hoisting and lowering modules 130b for simultaneously pressing the lower edge of the outermost edge of each unit swash plate 121, i.e., the lower edge of the outer edge side.

Therefore, when the central lift module 130a is lifted and lowered individually, the central side edge A of the entire unit swash plate 121 is raised or lowered simultaneously to form a dent in the form of upward protrusion or a downwardly depressed dent And the outer peripheral elevating module 130b disposed on the periphery can produce a sloping slope or a roughly curved ground while separately raising and lowering.

As described above, by using the inclined plate portion 120 made up of a plurality of unit swash plates 121 capable of individually adjusting the angles, various kinds of ground shapes such as dull, pit, and curved landforms in actual fields such as uphill and downhill It is possible to maximize the exercise efficiency of the actual adaptive force required in the field.
