PURPOSE:To permit to effect good lubrication without employing sealing agent on the tip end of a lap by a method wherein an oil feeding hole is formed on a rotary scroll mirror plate so as to arrive at the sliding part around the mirror plate and oil, which arrives at the upper part of a crank shaft from an oil reservoir, is supplied to the hole. CONSTITUTION:The lubricating oil 15, reserved in the lower part of an enclosed casing 1, is supplied to the upper part of the crank shaft 6 by rotating the crank shaft 6 due to the centrifugal pump effect of the oil feeding hole 6b provided eccentrically in the crank shaft. The oil, which arrived at the upper end of the crank shaft 6, is passed through the oil feeding hole 10c, provided in the rotary scroll mirror plate 10b, and is ejected out of the peripheral part of the same mirror plate 10b to supply the oil to the sliding parts of an Oldham's ring 8 and the mirror plate 10b.
