Abstract
It is assumed that a distance between a center portion of fixed scroll end plate and an outer peripheral portion at a distal end of fixed spiral wrap of fixed scroll is Ds, and that a distance between a center portion of orbiting scroll end plate and a portion included in a bottom face of an orbiting spiral wrap of orbiting scroll and facing the outer peripheral portion at the distal end of the fixed spiral wrap of the fixed scroll is Do. Further, assuming that an orbiting radius of orbiting scroll is ε, the orbiting radius being a distance between a center of eccentric shaft and a center of driving shaft, a relationship Ds+ε≤Do is satisfied.
