(54) Scroll compressor


(57) A scroll compressor including a stationary scroll (41) having a spiral-shaped stationary spiral structure (47) that is vertically provided on one surface of a stationary end plate (45) secured at a stationary-side support position (F) positioned at an outer circumference; and an orbiting scroll (43) having an orbiting end plate (51) that is provided with a spiral-shaped orbiting spiral structure (53) vertically on one surface thereof to be meshed with the stationary end plate (45), and that is supported at a position closer to a center than the stationary-side support position (F) in a manner that allows a revolving motion; wherein, for at least one of a clearance between a tip portion of the stationary spiral structure (47) and the orbiting end plate (51) and a clearance between the orbiting spiral structure (53) and the stationary end plate (45), the clearance (S1) at a side further outward than the orbiting-side support position (C) is made larger than the clearance (S2) at the center side.
