FIG. 6 shows a hexagonal cup. In addition, the installation of the oil supply pipe (11) to the cup (10) must be adjusted so that the oil supply pipe (11) is directly below when the cup (1o) is tightened to the bearing plate (9) with the appropriate torque. In addition, the male thread of the bearing plate (9) and the cup (
The machining accuracy of the female thread in 10) does not need to be very high for the rollers and cylinders (not shown), but the machining precision is much better than that of general bolts and nuts, and the machining accuracy of the female thread in the bearing plate (9) and cup (10) Both screws must be formed so that there is no leakage from the fitted portion of the female screw.

The oil supply pipe (11) of the horizontal rotary compressor of the present invention pumps up lubricating oil during operation. At this time, connect the male screw of the bearing plate (9) and the cup (
The part that fits with the female screw (10) is in surface contact and is completely sealed, so there is no leakage and the amount of lubricant pumped up does not decrease. Further, even if a small leakage portion occurs, the lubricating oil will seal this leakage portion, so the amount of lubricating oil pumped will not decrease.
