PURPOSE: A structure for supporting gas compression force of a scroll compressor is provided to reduce gas compression force acting on a rotary scroll. CONSTITUTION: A structure includes a rotary scroll(30) placed between a frame and a fixed scroll(20) fixed and joined to be separated from the frame, and engaged with the fixed scroll to rotate; a rotary axis(40) receiving driving force of an electromotive mechanism part to transmit to the rotary scroll; and a force dispersing type connecting unit connecting the rotary axis and the rotary scroll, and dispersing driving force transmitted through the rotary axis to the rotary scroll in axial direction and radial direction to transmit. The force dispersing type connecting unit includes a hub part(33) protruding from an end plate(31) of the rotary scroll; and a conical insertion groove(36) formed on an inside of the hub part. An eccentric part(41) is placed on one side of the rotary axis eccentrically to an axis. A conical first bush(80) is formed correspondingly with the conical insertion groove, and joined to the conical insertion groove. A conical second bush(90) has a penetrating hole(92) formed in a circular cone(91), and allowing the eccentric part to be inserted thereto, and is inserted to the conical first bush so that the penetrating hole is inserted to the eccentric part.
