るスクイズフイルムダンパ式軸受構造。 In a squeeze film damper type bearing structure in which a predetermined damper gap is formed between the outer circumferential surface of the bearing and the inner circumferential surface of the bearing holding member, and lubricating oil is supplied into this damper gap to form a squeeze film damper. , the outer circumferential surface of the bearing is formed to be rotatable, and the width of the outer circumferential surface of the bearing and the width of the inner circumferential surface of the bearing holding member are partially changed in a part of the circumference, so that the two face each other across the damper gap. A squeeze film damper type bearing structure, characterized in that the area is configured to change according to the rotational position of the bearing outer peripheral surface, and the initial rotational position of the bearing outer peripheral surface is held at a predetermined position via a spring member.
