    摘要: In a bearing mechanism according to a preferred embodiment of the present invention, a seal portion in which a surface of a lubricating oil is located is defined in a seal gap defined between an outer circumferential surface of a first tubular portion and an inner circumferential surface of a second tubular portion. The first tubular portion includes, in an area where the outer circumferential surface of the first tubular portion is in contact with the lubricating oil, a maximum outside diameter portion at which the outside diameter of the first tubular portion is greatest, an annular shoulder portion including a surface facing toward the surface of the lubricating oil and at which the outside diameter is smaller than at the maximum outside diameter portion, and an inclined portion at which the outside diameter gradually decreases from the annular shoulder portion toward the surface of the lubricating oil.

    摘要: A blower fan includes a heat source contact portion. A side wall portion includes a tongue portion. In a plan view, The heat source contact portion is arranged to cover a portion of a region surrounded by a third imaginary straight line tangent to an outer circumferential surface of a blade support portion and extending in parallel with the second imaginary straight line toward the air outlet in the first region, a fourth imaginary straight line tangent to the outer circumferential surface of the blade support portion and extending in parallel with the first imaginary straight line in the third region, the outer circumferential surface of the blade support portion, and the air outlet.
