Abstract
A scroll fluid machine includes a fixed scroll member having an end plate which is formed such that a central portion of the end plate which corresponds approximately to 1.5 to 2 turns of a wrap portion from its spiral starting end (innermost end) is a thick-walled portion having a relatively large plate thickness, and an outer peripheral portion of the end plate which lies radially outside the thick-walled portion is a thin-walled portion. The thickness of the thick-walled portion is set to be about 1.4 to 1.6 times the thickness of the thin-walled portion. By reducing thermal resistance at the thick-walled portion of the end plate, heat from compression chambers are conducted to radiating fins, thereby suppressing the transfer of the heat to the thin-walled portion.
