Due to the force acting in the direction, the way is pressed against the vertical reference surface of the bed, and at the same time, the way can be installed by being pressed against the horizontal reference surface of the bed.
Furthermore, by abutting the track base against the vertical reference plane and the horizontal reference plane, it is possible to maintain the mounting accuracy of the track base and provide rigidity against forces (external loads in the vertical and horizontal directions) applied to the track base.
特に、軸方向に“長”方形状の固定片により固

を締付けるにもかかわらず軌道台の取付け精度と
剛性が得られる（横方向も同じ）。 In particular, since it is fixed by a "long" rectangular fixing piece in the axial direction, the force that tightens the mounting bolts is distributed almost evenly and dispersed as the force that presses the way, so it can be mounted with the same force as before. Even though the bolts are tightened, the mounting accuracy and rigidity of the track can be obtained (the same applies in the lateral direction).
