Therefore, when bending in 5 directions by using 5 girders, the bending between the girders is within 2.3 degrees, the gap between the girders is kept within 50 mm, the installation site is minimized and the operation linearity is optimized.

Therefore, it is possible to carry out the branching operation stably while refracting each of the girders more uniformly compared with the conventional one, and the branching unit at the curve running of the magnetic levitation train sets the stable arc of the rail, thereby helping to improve the performance.

When the movable girder body is moved, the first and second crank arms 800 and 800 'rotate together with the movable girder body by the first and second motors 900' and 900 '. That is, the first and second crank arms 800 and 800 'perform the idle motion in which the first and second crank arms 800 and 800' move together with the movable girder body while rotating with respect to the movable girder body.

On the other hand, the movable girder main body is fixed by two third arm guides (700 ') in the middle. If the fixed girder 100 having a high frequency of use is disposed in the middle 3way, there is an advantage that the accuracy is further increased.

As a result, the first and second crank arms 800 and 800 'are structured so as to ride over the first and second arm guides 700 and 700', respectively, so that the first and second crank arms 800 and 800 'can be branched in five directions.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims .
