An inleakageproof structure for escape opening of a coil-type compressor. An outer wall face of the fixed coiled body of the compressor is formed with an annular oil groove around the escape opening. The oil groove is formed within a range covered by the valve plate. A valve plate is disposed on the outer wall face of the fixed coiled body corresponding to the escape opening. An oil liquid exhausted from the escape opening is contained in the oil groove. By means of capillarity of the oil liquid in the oil groove, the oil liquid automatically seals a gap between the valve plate and the outer wall face of the fixed coiled body.
