SLIDING BEARING STRUCTURE AND SCROLL COMPRESSOR

The purpose of the invention is to obtain a sliding bearing structure in which oil film pressure is effectively increased between a rotating shaft and a sliding bearing of a scroll compressor, and galling of the rotating shaft and the sliding bearing is minimized. A sliding bearing structure (50) and a scroll compressor (100) according to the present invention are provided with a rotating shaft (6) that drives an oscillating scroll of the scroll compressor, and a sliding bearing (15) that supports a diametrical load of the rotating shaft. The rotating shaft (6) is provided with axially extending grooves (20) in an outer peripheral surface that faces the sliding bearing (15), the grooves (20) are formed so as to cause a pumping effect, and the outer peripheral surface of the rotating shaft (6) is provided with a region P set in a prescribed angular range along the circumferential direction of the outer peripheral surface, and a region Q constituting the rest of the outer peripheral surface other than the regio
