This compressor is provided with: a rotor casing (3) that encircles a rotor, which rotates around an axis of rotation, from the outer peripheral side, and demarcates a primary duct for air (A) in the space with respect to the rotor; an air bleed chamber casing that is provided to the outer peripheral side of the rotor casing (3) and demarcates an air bleed chamber interconnecting to the primary duct via a slot (13) formed extending in the peripheral direction; and an air bleed tube (15) that is connected to the air bleed chamber casing from the outer peripheral side, and at the inside of which an air bleed pathway is formed that leads air (A) from with-in the air bleed chamber to the outside. In the slot (13), at which an opening (13a) to the primary duct is formed, a large opening (20), at which the opening area of the opening (13a) is locally larger than that of the other positions in the peripheral direction (Dc) of the opening (13a), is formed at a position in the peripheral direction (Dc) corresponding to the position at which the air bleed tube (15) is provided. |
