Abstract
A scroll compressor includes a housing, a rotary shaft, a movable scroll, an eccentric shaft, an opposed wall, a looped elastic plate, a looped support portion, an annular protrusion, a back pressure chamber, and a back pressure supplying groove. The distance in the radial direction of the rotary shaft from the rotation axis of the rotary shaft to then outer end of the back pressure supplying groove in the radial direction of the rotary shaft is shorter than or equal to the distance obtained by subtracting the distance in the radial direction of the rotary shaft between the rotation axis of the rotary shaft and the axis of the eccentric shaft from the distance in the radial direction of the rotary shaft from the axis of the eccentric shaft to the part of the protrusion that contacts the elastic plate.
