Abstract
The present invention has as an object providing a scroll compressor that transmits rotation of the eccentric axle side end plate of the orbiting scroll to the involute wrap side end plate with good efficiency, and sufficiently presses the involute wrap side end plate continuously against the fixed scroll without causing friction with the seal member; in order to attain this object, the present invention provides a scroll compressor providing a fixed scroll comprising an end plate and an involute wrap provided on one face of the end plate, and an orbiting scroll comprising and end plate, an engagement part provided on one face of the end plate and accommodating an eccentric axle therein, and an involute wrap provided on the other face of the end plate and forming a plurality of compression chambers by the combination with the involute wrap of the fixed scroll, wherein the end plate of the orbiting scroll is divided along the axial direction thereof into an involute wrap side end plate providing an involute wrap and an eccentric axle side end plate providing the engagement part, and furthermore, wherein a transmission mechanism is provided that permits movement of this involute wrap side end plate in the axial direction with respect to the eccentric axle side end plate but prevents movement in the radial or peripheral directions, and transmits the orbital movement of the eccentric axle side end plate to the involute wrap side end plate.
