A vane-type rotary compressor has a compression chamber delimited by a cylinder and front and rear covers secured to opposite ends of the cylinder. The front cover accommodates main and auxiliary shaft seal parts held in contact with a drive shaft. A space defined between the two shaft seal parts communicates with a suction stroke portion of the compression chamber via at least one bypass passage. Accordingly, the pressure and temperature acting on the main shaft seal part are substantially the same as those acting on the suction stroke portion, thus reducing the pressure and temperature on the main shaft seal part.
