<p>The reliability of a rear shaft is enhanced without using a separate element such as a reinforcing ring. A compressor (1) is provided with a cylinder body (8) having a compression chamber (11); a crank shaft (5) having an eccentric shaft portion (14) housed in the inside of the compression chamber (11), and a first shaft portion (5f) and a second shaft portion (5r) which are arranged on opposite sides of the eccentric shaft portion (14); a first head member (9) which is arranged at one end of the cylinder body (8) and which is capable of supporting the first shaft portion (5f); a second head member (10) which is arranged at the other end of the cylinder body (8) and which is capable of supporting the second shaft portion (5r); and an annular member (15) which is fitted on the eccentric shaft portion (14) in the inside of the compression chamber (11). In a side view, the central position (P1) of the eccentric shaft portion (14) arranged in the inside of the compression chamber (11) in the axial direction is located closer to the second shaft portion (5r) than the central position (P2) of the compression chamber (11) in the axial direction.</p> |
