受構造。 In a bearing structure having a cylindrical bearing metal that is press-fitted into a hole formed in a housing and rotatably supports a rotating shaft by its inner circumferential surface, the direction of the rotational axis formed on the inner circumferential surface of the bearing metal a plurality of oil grooves extending from one side to the other; a protruding strip formed on the outer circumferential surface between each of the oil grooves to press against the inner circumferential surface of the hole in the housing; and an inner circumferential surface of the housing hole formed between each protruding strip on the outer circumferential surface. When the bearing metal is press-fitted into the hole of the housing, each protrusion comes into pressure contact with the inner circumferential surface of the hole, and the space between the protrusions curves outward. A bearing structure made of bearing metal characterized by the inner peripheral surface of the bearing metal being a continuous, smooth arc-shaped surface.
