Abstract
The present invention addresses the problem of providing a rotary shaft supporting structure which is capable of supporting a rotary shaft for a longer period. This rotary shaft supporting structure, which supports a rotary shaft on which a thrust collar that protrudes outwards in the radial direction is formed, has: thrust bearings which face the thrust collar, and support, using support surfaces, the thrust collar surfaces that are orthogonal to the axial direction of the rotary shaft; and support mechanisms which support the thrust bearings in the axial direction from the surface side of support surfaces at the opposite side to the thrust collar. The sides of the support mechanisms that face the end surfaces of the thrust bearings are inclined in the direction orthogonal to the direction in which the rotary shaft tilts.
