摘要： In a scroll fluid compressor including orbiting and stationary scroll members having end plates and wraps in vortical form in upstanding positions on the end plates meshing with each other to define therebetween spaces for compressing a fluid introduced through an inlet line and discharging the compressed fluid through an outlet line, flat plates in vortical form having surface finishes of higher precision than the end plates are placed in valleys between the outer wraps and the inner wraps of the scroll members to enable the wrap of the orbiting scroll member to move in orbiting movement while having the forward ends of the wraps in sliding contact with the surfaces of the flat plates in vortical form. Stepped portions may be formed on the bottoms of the valleys to hold the flat plates in vortical form in place, or space may be provided between the flat plates in vortical form and the bottoms of the valleys to be filled with a filler material from outside through ducts formed in the end plates, to bond the flat plates in vortical form to the end plates to enable the forward ends of the wraps to be maintained in uniform contact with the flat plates in vortical form.
