SCROLL COMPRESSOR AND REFRIGERATION CYCLE DEVICE

An orbiting base plate of an orbiting scroll has formed therein: an oil flow passage for allowing oil supplied from an oil supply flow passage to flow from a radially inner side toward a radially outer side; a spiral side oil supply hole providing communication between the oil flow passage and a spiral forming surface, which is the surface of the orbiting base plate on the side on which an orbiting spiral body is formed; and a thrust surface side oil supply hole providing communication between the oil flow passage and a thrust surface on the opposite side of the orbiting base plate to the spiral forming surface. An opening and closing mechanism which closes the thrust surface side oil supply hole when the oil pressure of oil pumped from an oil reservoir by means of an oil pump and supplied into the oil flow passage is low, and which opens the thrust surface side oil supply hole when the oil pressure is high, is disposed in the oil flow passage. 在摆动涡旋件的摆动台板形成有：油流路，其使从供油流路供给的油从径向内侧朝向径向外侧流动；涡旋侧供油孔，其使油流路与摆动台板的摆动涡
