<P>PROBLEM TO BE SOLVED: To suppress, as much as possible, reduction in rigidity of a compressor casing, which comprises a cylindrical body section and a bottomed cylindrical end plate section joined thereto. <P>SOLUTION: In the compressor casing, an inner diameter d4 of cylindrical sections 12b, 13b in end plate sections 12, 13 is smaller than an inner diameter d1 of an opening end of a body section 11. Thereby, the rigidity of the end plate sections 12, 13 can be increased compared to a case where the inner diameter d4 of end plate sections 12, 13 is not smaller than the inner diameter d1 of the body section 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
