Abstract

PURPOSE: To reduce frictional loss between a shaft and a bearing by providing a bearing member having a recessed part with an area less than one eighth of the whole inner surface and with a fixed depth in a main and a sub bearings at the circumferential angel of less than 90° from a vane in the reversely rotating direction of the shaft.
CONSTITUTION: The recessed part 18a provided on the inner diameter side of a bearing member 18 fitted into a main bearing 7 is positioned within at least 90° from the position of a vane 6 in the reversely rotating direction of a shaft 3, and its area is made less than one eighth of the whole inner surface area. With this structure, the shaft 3 is eccentric approximately in the range of 120°θ1-180°θ2 due to the load acted upon the shaft 3 at the time of operation, so that frictional loss generated by the friction between the fluid and lubricating oil supplied between the shaft 3 and the bearing member 18 is decreased by providing the recessed part 18a at the bearing member 18 on the reverse eccentricity side of the shaft 3. In addition fluid friction is scarcely generated by making the depth of the recessed part 18a 0.1-0.5mm, so that frictional loss can be reduced.
