Abstract
An object of the present invention is to decrease the diameter of end plate of a fixed scroll and the diameter of orbiting locus circle of an orbiting scroll, by which the inside diameter of a housing is reduced, thereby the apparatus being made compact. The constitution is such that the center P of the end plate 211 of the fixed scroll 21 lies on the straight line D starting at the wrap end point T of the outermost end of the spiral wrap 212 and passing through the involute unrolled angle position C of the base circle A and at the position shifting one-half the orbiting radius a in the direction reverse to the outermost wrap end of the spiral wrap 212.
