Abstract
A shaft includes: two large-diameter portions; and a small-diameter portion formed between the two large-diameter portions. A bearing includes: an annular body in which to insert the shaft; two bearing surfaces being opposite the large-diameter portions; and an intervening surface located between the two bearing surfaces on an inner circumferential surface of the body, and being opposite the small-diameter portion with a clearance formed between the intervening surface and the small-diameter portion. No anti-corrosion treatment is applied to the large-diameter portions. An anti-corrosion treatment is applied to at least any one of: an exposed portion of an outer peripheral surface of the body of the bearing, which is exposed to the outside of the housing; the intervening surface of the bearing; an opposite end surface of the bearing; and the small-diameter portion of the shaft.
