Abstract: A scroll fluid machine includes a revolving scroll in which a revolving wrap stands upright on an end plate supported revolvably on a drive shaft, and a fixed scroll which is provided opposite the revolving scroll and in which a fixed wrap stands upright on an end plate. The revolving and fixed wraps overlap to form a compression chamber for compressing a fluid by causing the revolving scroll to revolve. The scroll fluid machine further includes a rod-shaped member attached to the end plate of the revolving scroll and extending to a rear surface side of the fixed scroll, which is a side not opposing the revolving scroll. A revolving plate is attached to the rod-shaped member, provided with a pin crank mechanism, and supported revolvably on the drive shaft. The revolving plate is provided with a sealing unit that seals the compression chamber in an axial direction.
