Abstract
A suction casing includes a suction nozzle that introduces a fluid from an outer circumferential side to an inner circumferential side in a radial direction; and a chamber that includes a substantially doughnut-shaped space in communication with an inside of the suction nozzle on the outer circumferential side and that guides the fluid, introduced from the suction nozzle, to an inlet opening portion opening in an axial direction and disposed in a substantially annular shape. The chamber is formed so that a radial width is narrower in a circumferential direction from a joint portion in communication with the suction nozzle to an opposite side across a central axis.
