Abstract

A motor-driven scroll type compressor that includes: a housing; a rotary shaft; an electric motor; and a compression part including a fixed scroll and an orbiting scroll. The housing includes a separation wall separating a back pressure chamber from a motor chamber. The separation wall includes a bearing and a seal member having an inner circumference seal portion and an outer circumference seal portion. The seal member seals the back pressure chamber and the motor chamber. An end of the inner circumference seal portion is provided closer to the bearing than an end of the outer circumference seal portion is. The separation wall includes a holding portion being in contact with the end of the outer circumference seal portion to restrict movement of the seal member toward the bearing. The end of the inner circumference seal portion is provided closer to the bearing than the holding portion is.
