油式スクロール流体機械。 a casing, a drive shaft rotatably provided on the casing, an orbiting scroll rotatably provided on the drive shaft via a bearing boss portion and having a spiral wrap portion erected on an end plate; An oil-free scroll fluid machine consisting of a fixed scroll fixed to a casing and having a spiral wrap section erected on an end plate so as to overlap the wrap section of the orbiting scroll and form a compression chamber while rotating. At a position at least radially inward from the bearing boss portion of the orbiting scroll, the axial clearance between the tip of the lap portion of the orbiting scroll and the end plate sliding surface of the fixed scroll is defined as the tip of the lap portion of the fixed scroll. An oil-free scroll fluid machine characterized in that the axial clearance between the orbiting scroll and the sliding surface of the end plate is set to be larger than the axial clearance.
