Abstract
A scroll fluid machine includes: a casing; a fixed scroll having an end plate, a spiral wrap part provided on the end plate, and a flange provided outside the wrap part and fitted to the casing; and an orbiting scroll having an end plate and a spiral wrap part provided on the end plate with a plurality of compression chambers formed in a space up to the wrap part of the fixed scroll, which is provided to perform an orbiting motion, wherein the flange is provided with a deformation absorbing part which absorbs deformation due to thermal expansion of the end plate. The scroll fluid machine is improved in reliability while the compression efficiency is maintained by preventing the fixed scroll and the orbiting scroll from coming into contact with each other without increasing a clearance between the wrap parts of both scrolls.
