This paper deals with a calculation method of free vibration of the moving belt of which axial tension, bending rigidity and rotary inertia are taken into consideration. By considering the moving belt the enough long simply supported beam with two pairs of moving rollers, the vibration of the moving belt is considered forced vibration by unknown forces and bending moments at positions of rollers. Using conditions of constraint that both displacements and slopes at the positions of rollers should be zero, simultaneous integral equations of Volterra type are obtained. The solution of the free vibration of the moving belt is obtained by solving these simultaneous equations numerically. Static displacement, divergent solution or vibrating solution is obtained in accordance with axial tension and moving speed of the belt.
