A centrifugal compressor comprising a scroll structure, an impeller, a diffuser which is provided on an outer circumferential side of the impeller (5, 7) and a scroll flow path which is formed in a spiral shape that is connected to an outer circumference of the diffuser, wherein an axial cross-sectional shape of the scroll flow path is a roughly circular shape, the roughly circular shape is formed from a scroll chamber which juts out in the axial direction relative to the position of the diffuser outlet and a shift chamber (32, 38a, 40) that forms a remainder of the roughly circular shape in an axial direction opposite to the scroll chamber, the shift chamber is formed such that a diffuser outlet is axially shifted to a position which is closer to a circle center with respect to the roughly circular cross-sectional shape of the scroll flow path than to a position of a tangent line to the roughly circular shape, and which does not reach the circle center, and, if a winding angle θ in a clockwise direction is set so that a line connecting a position of a tongue portion and the circle center, in a view from an axial line direction of a rotary shaft, is at a position of approximately 60 degrees as a winding angle θ of the scroll flow path, the shift chamber (32, 34, 38a, 38b, 40) is formed on at least a winding end portion of the scroll flow path, the winding end portion being located in an area where the winding angle θ exceeds 360 degrees in a circumferential direction of a spiral, characterized in that the shift chamber (32, 34, 38a, 38b, 40) starts shifting from a position where the winding angle θ is approximately 180 degrees and increases so as to reach maximum at a position where the winding angle θ is approximately 360 degrees, wherein a shift amount increases linearly or parabolically as the winding angle θ increases. a scroll structure, an impeller, a diffuser which is provided on an outer circumferential side of the impeller (5, 7) and a scroll flow path which is formed in a spiral shape that is connected to an outer circumference of the diffuser, wherein an axial cross-sectional shape of the scroll flow path is a roughly circular shape, the roughly circular shape is formed from a scroll chamber which juts out in the axial direction relative to the position of the diffuser outlet and a shift chamber (32, 38a, 40) that forms a remainder of the roughly circular shape in an axial direction opposite to the scroll chamber, the shift chamber is formed such that a diffuser outlet is axially shifted to a position which is closer to a circle center with respect to the roughly circular cross-sectional shape of the scroll flow path than to a position of a tangent line to the roughly circular shape, and which does not reach the circle center, and, if a winding angle θ in a clockwise direction is set so that a line connecting a position of a tongue portion and the circle center, in a view from an axial line direction of a rotary shaft, is at a position of approximately 60 degrees as a winding angle θ of the scroll flow path, the shift chamber (32, 34, 38a, 38b, 40) is formed on at least a winding end portion of the scroll flow path, the winding end portion being located in an area where the winding angle θ exceeds 360 degrees in a circumferential direction of a spiral, characterized in that the shift chamber (32, 34, 38a, 38b, 40) starts shifting from a position where the winding angle θ is approximately 180 degrees and increases so as to reach maximum at a position where the winding angle θ is approximately 360 degrees, wherein a shift amount increases linearly or parabolically as the winding angle θ increases.
