    Abstract: A scroll compressor of the present invention includes a partition plate, a fixed scroll, an orbiting scroll, a rotation-restraining member, a main bearing, a discharge space, a ring-shaped first seal member and a ring-shaped second seal member. A pressure in the medium pressure space is set lower than that in the discharge space and higher than that in the low pressure space. The first seal member and the second seal member are sandwiched by the partition plate by means of a closing member, the fixed scroll can move in an axial direction of the fixed scroll between the partition plate and the main bearing. If a high pressure is applied to the discharge space, the fixed scroll can be pressed against the orbiting scroll.
