Abstract
The orbiting base plate has a compression side surface and a back pressure chamber side surface. The gas passage has an opening in the compression side surface of the orbiting base plate between portions of the orbiting spiral wall that face each other, and the gas passage has an opening in the back pressure side surface at a position that faces an area on a radially inner side than the outer circumference of the bearing, so as to feed the refrigerant gas in the compression chamber to the back pressure chamber.
