Abstract (en)

[origin: EP3109475A1] It is an object of the present invention to realize reliability improvement and a long life of a rotation preventing mechanism by preventing heat from being directly transferred from an orbiting scroll to a rotation preventing mechanism. The present invention includes a fixed scroll, an orbiting scroll provided to be opposed to the fixed scroll and moved to orbit, a casing provided on an outer side of the orbiting scroll, a driving shaft for driving the orbiting scroll, a back face plate fastened to the orbiting scroll and connected to the driving shaft by a boss portion, and a rotation preventing mechanism provided between the casing and the boss plate for preventing a rotation of the orbiting scroll, in which the back face plate includes a rotation preventing mechanism side back face plate integrally provided with the rotation preventing mechanism and a driving shaft side back face plate integrally provided with the boss portion, and the rotation preventing mechanism side back face plate is not in contact with the orbiting scroll.
