- 1. A scroll type compressor comprising:
- a hermetic shell which is constituted by a cylindrical center shell, and dish-shaped end shells closing both ends of the center shell and fixed to the center shell by continuously welding the end shells to the center shell at their circumference;
- a fixed scroll and an orbiting scroll which are housed in the hermetic shell, and which gradually compresses an inspired refrigerant gas in a compression chamber formed by combining scroll wraps, and discharges the compressed gas;
- a main shaft rotated by an electric motor to drive the orbiting scroll;
- a frame having a peripheral portion fixed to the center shell, and supporting the main shaft at one of its ends; and
- a subframe having a peripheral portion fixed to the center shell by spot welding, and supporting the main shaft at its other end;
- wherein the welding starting point of the continuous welding for fixing the end shells to the center shell is arranged to be in the same position when viewed in the axial direction on the circumference of the center shell as one of the welding points of the spot welding for fixing the subframe to the center shell.
