To lighten a compressor and to keep the predetermined accuracy in size before assembling, even after the assembling by fixing a bearing holding member on a closed housing, and mounting a compressor mechanism part in the closed housing through this bearing holding member.
In a horizontal scroll compressor C, a compressor mechanism part 4 and a motor part 6 are accommodated in a closed housing 2, and a movable scroll 4b revolves while engaged with a fixed scroll 4 fixed inside of the closed housing 2 in the compressor mechanism part. A movable scroll shaft 4c is projected at a back side of the movable scroll 4b, and this movable scroll shaft 4c is loosely inserted into an eccentric bearing 10 mounted on one end of a crank shaft 8. On this occasion, one end of the crank shaft 8 is rotatably supported by a bearing component 14 through a main bearing 12, and the bearing component 14 is held by a bearing holding member 20 welded and fixed on the closed housing 2. Further the other end of the crank shaft 8 is rotatably supported by a sub-bearing 18 held by a bearing component 16.
