Abstract
The objective of the present invention is to provide a scroll-type fluid machine for which the service life can be improved by reducing the load applied to a rotation prevention mechanism. To solve this problem, this scroll-type fluid machine is characterized by being equipped with a stationary scroll, an orbiting scroll that is provided opposing the stationary scroll and undergoes turning movement, a casing provided on the outside of the orbiting scroll, a drive shaft that drives and turns the orbiting scroll, a boss plate part that is provided separated from the orbiting scroll and is connected to the drive shaft, and multiple rotation prevention mechanisms provided between the boss plate part and the casing, and is characterized in that the boss plate part has multiple rotation-prevention-mechanism-side boss plate parts connected to the rotation prevention mechanisms, and a drive-shaft-side boss plate part connected to the drive shaft, and spaces are provided between the rotation-prevention-mechanism-side boss plate parts and the drive-shaft-side boss plate part.
