A compressor casing, a compressor provided with the same, and a method of assembling the compressor are provided. The compressor casing includes a substantially tubular casing, a plurality of sealing surfaces provided on an inner circumferential surface of the compressor casing along an axial direction thereof, a sealing means provided for each of the plurality sealing surfaces, a substantially cylindrical bundle for accommodating a blade inside and for being assembled to the compressor casing so as to have contact with the plurality of sealing surfaces, and a roller provided on an outer circumferential surface of the substantially cylindrical bundle, for rolling on the inner circumferential surface of the compressor casing when the substantially cylindrical bundle is assembled to or removed from the compressor casing. The sealing surfaces are connected with one another with tapered surfaces.

1. A compressor comprising: a substantially tubular casing;a substantially cylindrical bundle accommodating a blade inside, for being assembled to the casing; anda roller provided on an outer circumferential surface of the bundle, for rolling on an inner circumferential surface of the casing when the bundle is assembled to or removed from the casing,wherein the casing comprises a plurality of sealing surfaces provided on the inner circumferential surface of the casing so that the sealing surfaces are arranged in series along an axial direction of the casing with an interval between each of successive sealing surfaces,wherein the bundle comprises: sealing portions which are provided on the outer circumferential surface of the bundle and which face the sealing surfaces, respectively, when the bundle is assembled to the casing,two or more sealing means which are provided on respective outer circumferential surfaces of the sealing portions and are configured to extend along a circumferential direction of the casing, and come into contact with the sealing surfaces, respectively, when the bundle is assembled to the casing,wherein a distance of each interval is longer than a length of each of successive sealing surfaces, andwherein each interval is defined by a respective portion of the casing which connects successive sealing surfaces to each other that is tapered off as a whole in a direction of assemblage of the bundle and has a gradual inclination relative to an axis of the bundle. 2. The compressor according claim 1, wherein: the sealing portions are arranged in series along an axial direction of the bundle with an interval between each of successive sealing portions being defined by a respective portion of the bundle which connects successive sealing portions to each other that is tapered off as a whole in the direction of assemblage of the bundle, andeach respective portion of the bundle which connects successive sealing portions to each other has an inclination angle, respectively, that is steeper than each respective portion of the casing which connects successive sealing surfaces to each other. 3. A method of assembling a compressor, wherein the compressor is configured to include: a substantially tubular casing;a substantially cylindrical bundle accommodating a blade inside, for being assembled to the casing; anda roller provided on an outer circumferential surface of the bundle,wherein the casing comprises a plurality of sealing surfaces provided on an inner circumferential surface of the casing so that the sealing surfaces are arranged in series along an axial direction of the casing with an interval between each of successive sealing surfaces,wherein the bundle comprises:sealing portions which are provided on the outer circumferential surface of the bundle and which face the sealing surfaces, respectively, when the bundle is assembled to the casing,two or more sealing means which are provided on respective outer circumferential surfaces of the sealing portions and are configured to extend along a circumferential direction of the casing, and come into contact with the sealing surfaces, respectively, when the bundle is assembled to the casing,wherein a distance of each interval is longer than a length of each of successive sealing surfaces,wherein each interval is defined by a respective portion of the casing which connects successive sealing surfaces to each other that is tapered off as a whole in a direction of assemblage of the bundle and has a gradual inclination relative to an axis of the bundle, andwherein the bundle is assembled into or removed from the casing, using the roller provided on the outer circumferential surface of the bundle which rolls on the inner circumferential surface of the casing. 4. The method according claim 3, wherein: the sealing portions are arranged in series along an axial direction of the bundle with an interval between each of successive sealing portions being defined by a respective portion of the bundle which connects successive sealing portions to each other that is tapered off as a whole in the direction of assemblage of the bundle, andeach respective portion of the bundle which connects successive sealing portions to each other has an inclination angle, respectively, that is steeper than each respective portion of the casing which connects successive sealing surfaces to each other.
