To provide a machine tool supporting mechanism capable of eliminating the movement or shaking of a machine caused by the vibration of the machine itself.

A bolt 3 is placed in a recessed part in the center of the upper surface of a leveling plate 4 having a truncated cone shape. The supporting bolt 3 upright on the leveling plate 4 installed on a floor surface 5 is engaged with a female screw part provided in a bed 2, and the height and balance of the bed 2 are adjusted by the engaging action between the supporting bolt 3 and the female screw part of the bed 2. In the backside of the leveling plate 4, an anti-skid sheet 1 having large friction resistance is stuck by curing type adhesive (double-liquid epoxy resin).
