A scroll-type compressor comprising a stationary scroll member having a spiral-shaped wrap, an orbiting scroll member interleaved with said stationary scroll and having a spiral-shaped wrap of the same shape as that of the wrap of the stationary scroll member but performing an orbital motion without rotation, a compression chamber defined between the wraps of the scroll members, a crankshaft eccentrically connected to the orbiting scroll member for causing the orbiting scroll member to orbit, and a sealing apparatus for restraining radial leakage of compressed fluid. The sealing apparatus comprises elastic thrust bearing members for elastically supporting the stationary scroll in order to allow the stationary scroll to wobble upwardly and downwardly as the orbiting scroll performs the orbital motion simultaneously with wobbling upwardly and downwardly due to a pressure difference between the outside and the inside of the compression chamber. The invention provides advantage in that the upward and downward wobbling of the stationary scroll efficiently results in closely contacting ends of the warps with bottom surfaces of the surfaces of the scrolls, thereby restraining formation of radial clearances between the scrolls.
