A scroll compressor comprising: a rotary shaft extending along an axis and rotating about the axis; a turning scroll which is capable of revoluting around the axis at a position offset with respect to the axis; a fixed scroll opposite to the turning scroll and configured to form a compression chamber that compresses a coolant; and a bush assembly installed at the rotary shaft and configured to rotatably support the turning scroll, wherein the bush assembly comprises: a bush fixed to the rotary shaft and configured to rotatably support the turning scroll at a position offset with respect to the axis; a ring section formed at an outer circumferential side to overhang from an outer circumferential surface of the bush; and a weight section formed at the outer circumferential side of the ring section and extending in an arc shape in a circumferential direction of the bush, characterised in that a first groove section is formed so as to recess inward in the radial direction of the axis from the outer circumferential surface of the bush and extending in the axis, a second groove section is formed so as to extend from the inside in the radial direction to the outside in the radial direction of the ring section and in communication with the first groove section, and a discharge section is formed so as to pass through the weight section in the radial direction and in communication with an end portion and of the outside in the radial direction of the second groove section. a rotary shaft extending along an axis and rotating about the axis; a turning scroll which is capable of revoluting around the axis at a position offset with respect to the axis; a fixed scroll opposite to the turning scroll and configured to form a compression chamber that compresses a coolant; and a bush assembly installed at the rotary shaft and configured to rotatably support the turning scroll, wherein the bush assembly comprises: a bush fixed to the rotary shaft and configured to rotatably support the turning scroll at a position offset with respect to the axis; a ring section formed at an outer circumferential side to overhang from an outer circumferential surface of the bush; and a weight section formed at the outer circumferential side of the ring section and extending in an arc shape in a circumferential direction of the bush, characterised in that a first groove section is formed so as to recess inward in the radial direction of the axis from the outer circumferential surface of the bush and extending in the axis, a second groove section is formed so as to extend from the inside in the radial direction to the outside in the radial direction of the ring section and in communication with the first groove section, and a discharge section is formed so as to pass through the weight section in the radial direction and in communication with an end portion and of the outside in the radial direction of the second groove section. a bush fixed to the rotary shaft and configured to rotatably support the turning scroll at a position offset with respect to the axis; a ring section formed at an outer circumferential side to overhang from an outer circumferential surface of the bush; and a weight section formed at the outer circumferential side of the ring section and extending in an arc shape in a circumferential direction of the bush, characterised in that a first groove section is formed so as to recess inward in the radial direction of the axis from the outer circumferential surface of the bush and extending in the axis, a second groove section is formed so as to extend from the inside in the radial direction to the outside in the radial direction of the ring section and in communication with the first groove section, and a discharge section is formed so as to pass through the weight section in the radial direction and in communication with an end portion and of the outside in the radial direction of the second groove section.
