The oil supply vane 15 is formed from a thin flat plate so that when unfolded as shown in FIG. 5, it has a substantially circular head portion 15a and a rectangular leg portion 15b. The head 15a also has an oil suction hole 15c inside and a slit 15dk opened in the longitudinal direction. , the head 15a is bent in opposite directions along the fold line 15f so as to have a substantially trapezoidal flat part 15e at the connection part with the leg part isb, and the ends of the slings 15d are bent in opposite directions to each other on the fold line 15f. The leg portions 15b are formed with an appropriate curvature so as to be in contact with each other, and the leg portions 15b are twisted into a spiral shape, resulting in the state shown in FIG. 6.

A compression mechanism section having a blade that fits into a groove provided in the body and moves back and forth with the tip of the blade in contact with the roller is fixed, and a lubricating oil is applied to the compression mechanism section. The shaft is housed in a vertical hole provided along the axis of the shaft, and has an oil suction hole on the inside and a slit that opens into the oil suction hole, and has a substantially conical head portion, and a spiral leg portion. The oil supply vane is attached and fixed, eliminating the need for a stopper that requires strict control of outside diameter accuracy as in the past.
In addition, since it is integrally machined from a thin flat plate, it has a more inexpensive structure, and also has the effect of ensuring reliable oil supply due to the flat part that prevents slippage between the lubricating oil and the inner diameter of the head. .
