PROBLEM TO BE SOLVED: To provide a rotating shaft supporting device capable of smoothly and stably rotating a heavy object. SOLUTION: This rotating shaft supporting device comprises a rotating shaft 1, a rotation-side ring body 10 externally fitted and fixed to the rotating shaft 1 and comprising a conical inclined face 14 inclined to the axial direction of the rotating shaft 1 on its outer periphery, a fixed-side ring body 16 comprising an insertion hole 17 for the rotating shaft 1 and further comprising a conical inclined face 18 relatively kept into contact with the conical inclined face 14 of the rotation-side ring body 10 at the circumference of the insertion hole 17, and a spring 20 fitted and mounted on the rotating shaft 1 for controlling contact pressure force between the conical inclined faces 14, 18 relatively kept into contact with each other, when the rotating shaft 1 is inserted into the fixed-side ring body 16.
