<p>PROBLEM TO BE SOLVED: To provide a compressor capable of preventing the partial contact of a bundle insertion roller with a casing inner circumference and suppressing degradation in the quality of the compressor.SOLUTION: A compressor that comprises: a cylindrical casing; a bundle 3 including a cylindrical stationary member and a rotor accommodated in the stationary member, and inserted into the casing; and a roller 11 supporting the bundle 3 and, at the same time, rolling on an inner circumferential surface of the casing when the bundle is inserted into the casing along an axial direction, and in which an outer circumferential surface 23 of roller 11 is formed on a continuous convex curved surface so that ends are smaller in a radius of curvature than a center along a rotational axis 21 of the roller 11 is provided.</p> |
