Claim 0:
1. A compressor, comprising:
a casing including a tubular barrel casing and an end casing covering an opening of an end portion of the tubular barrel casing;
a housing provided inside the casing;
a first weld formed by welding the tubular barrel casing and the housing together; and
a second weld formed by welding the tubular barrel casing and the end casing together over a predetermined length along a circumferential direction of the tubular barrel casing,
the second weld including a repeatedly welded portion formed by one end portion and an other end portion of the second weld overlapping each other, or the second weld including a plurality of second welds each including a repeatedly welded portion formed by an end portion of the second weld and an end portion of an other one of the second welds overlapping each other,
the repeatedly welded portion being formed to reduce deformation of the tubular barrel casing, and the repeatedly welded portion and the first weld being aligned along an axial direction of the tubular barrel casing,
with respect to the circumferential direction of the barrel casing, a width of the repeatedly welded portion to a width of the first weld aligned with the repeatedly welded portion along the axial direction, the width of the repeatedly welded portion is larger than or equal to the width of the first weld, and
the formed second weld being
a single second weld having a substantially circular shape or
a pair of second welds each having a substantially semicircular arc shape.
