In a scroll fluid machine, an orbiting scroll is eccentrically revolved
with respect to a stationary scroll so that fluid in a sealed chamber
between the stationary and orbiting scrolls may be compressed toward a
center. A first magnet is mounted on the stationary scroll and a second
magnet is mounted on the orbiting scroll so that the same poles of the
first and second scrolls may be opposite to each other thereby preventing
the orbiting scroll from pressing the stationary scroll excessively.
