摘要： PROBLEM TO BE SOLVED: To surely seal an oil feeding passage from an electric motor side space by providing, on a sub-bearing part, the oil feeding passage for feeding oil to the sub-bearing of the sub-bearing part and a seal member for partitioning the oil feeding passage from the electric motor-side space, and constituting the seal member so as to be capable of following the inclination or whirling of a rotating shaft. SOLUTION: A sub-bearing part is loaded on the opposite side to a compressing mechanism with an electric motor part between, it comprises a sub-bearing 804 integrated to a housing 801 and a seal member 805 provided on the upper part of the sub-bearing 804. The oil feed to the sub-bearing part is performed through an oil feed pipe mounted on the lower part of the sub- bearing part. Although a rotating shaft 300 touches with the seal member 805 by the inclination and whirling of the rotating shaft 300 to generate a load, an O-ring 808 is provided on the circumferential part of the seal member 805, whereby the O-ring 808 seals the sub-bearing part and also absorbs the load by its own deformation. Accordingly, the structure that generates no excessive load even if the rotating shaft 300 touches with the seal member 805 can be provided.

摘要： PROBLEM TO BE SOLVED: To prevent flaking, a gnawing and seizure of a ball or roller bearing by lack of oiling, and to enhance reliability by forming clearance between rolling bodies of the bearing as a part of an oiling passage connecting an inside or outside oil reservoir and an oiling hole in a rotary shaft. SOLUTION: A sub-bearing part 10 is formed as a structure having a seal member 10c in an upper part of a ball bearing 10a by installing the ball bearing 10a in a bearing box 10d. A horizontal hole 3c penetrating through a rotary shaft directional oiling hole 3b is arranged in an upper part of a fitting part with the ball bearing 10a in a rotary shaft 3. A closing member 3d is incorporated into the lower end of the rotary shaft 3. Oil of an oil reservoir enters the bearing box 10d via an oiling pipe 11 fixed to the bearing box 10d, passes through to an upper part of the ball bearing 10a by passing between rolling bodies 10b while lubricating the ball bearing 10a, and enters the oiling hole 3b from the horizontal hole 3c. The seal member 10c prevents mixing of refrigerant gas from the outside of the bearing box 10d or the outflow of the oil to the outside from the inside of the bearing box 10d.
