Reference numeral 9 denotes a side plate that integrally includes a bearing 9a that pivotally supports the crankshaft 6. The aforementioned side plate 5, cylinder plate 7, and side plate 9 are integrated with bolts 10, and the compression chamber 1
1 is defined. 12 is a vane that divides the compression chamber 11 into a high pressure side and a low pressure side; 13 is a vane that fixes one end of the bearing 9aK;
It is an oil pipe for sucking up oil with an arm bent downward, and its lower end is immersed in oil 14 stored below the sealed case 2. 15 is fixed to the end of the crankshaft 6 and is connected to the oil pipe 1
This is a coil spring for pumping up oil that is installed close to the inner surface of 3. 16 is a suction pipe attachment hole formed in the side plate 9, and 17 is a suction pipe extending parallel to the axis of the sealed case 2 and penetrating the lid portion 2b. This suction pipe 17 includes a press-fitting part 18, a bead-shaped press-fitting part 19,
Large diameter filter chamber 20. The insertion part 21 is integrally formed. This is formed by shrinking a pipe that has a large outer diameter in the filter chamber 20 so that the pipe has a smaller diameter on the press-fitting part 19 side and the inlet part 21 side. Reference numeral 22 denotes a communication passage that communicates between the compression chamber 11 provided in the cylinder plate 7 and the suction pipe attachment hole 16. 23 is a filter mounted inside the filter chamber 20.
また２４−は吐出管、２５は入口部２１の貫通孔である
。Further, 24 - is a discharge pipe, and 25 is a through hole of the inlet portion 21 .

固着し、蓋部２ｂを吸入管１７の入口部２１が貫通孔２
５を貫通するように胴部２ａにセットし、接合部を溶接
する。In this configuration, the suction pipe 17 and the side plate 9 are pre-assembled as shown in FIG. 2 using the press-fitting part 19 of the suction pipe 17 that houses the filter 23, the compression mechanism part 4 is assembled, and the body of the sealed case 2 is assembled. 2a together with the electric motor part 3, and the lid part 2b is inserted into the inlet part 21 of the suction pipe 17 through the through hole 2.
5, and the joints are welded.
従って、吸入管１７は予じめ圧縮機構部４に固定され、
かつ吸入管１７の方向と蓋部２ｂの取付方向が一致して
いるため、蓋部２ｂの組立が容易である。Therefore, the suction pipe 17 is fixed to the compression mechanism section 4 in advance,
Moreover, since the direction of the suction pipe 17 and the mounting direction of the lid part 2b match, the assembly of the lid part 2b is easy.

の効果を奏する。As described above, the present invention is such that the suction pipe is attached to the side plate that defines the compression chamber, and this suction pipe is press-fitted and fixed so as to extend in the axial direction of the sealed case. Since the direction in which the lid is set and the direction in which the suction pipe extends are the same, assembly is easy.Also, since the lid can be positioned, it is easy to connect the body and the lid, and the number of parts is reduced. This has the effect of reducing assembly man-hours.
