A rotary compressor includes a first compressing unit and a second compressing unit arranged one on top of another with a partition board therebetween. The partition board is provided with a vertical hole and a horizontal hole. After the front end of an injection copper tube to inject a refrigerant liquid is loose fit in the horizontal hole, an injection liner having an outer diameter larger than the inner diameter of the injection copper tube is inserted into the injection copper tube from the back end and is pressed up to the front end to increase the diameter of the front end of the injection copper tube such that the injection copper tube is tight fit in the horizontal hole. |
