A half bearing has a concave portion, a concave portion, and a concave portion penetrating from the outer circumferential surface to the inner circumferential surface, and the washer has a convex portion, a convex portion, and a convex portion on the inner circumferential surface side. The washer is moved to the outer circumferential surface side of the half bearing in a bent state, the convex portion is inserted into the concave portion, the convex portion is aligned with the position of the concave portion, and the convex portion is aligned with the position of the convex portion. Next, when the half bearing returns to its shape before being bent, the convex portion is accommodated in the concave portion, and the convex portion is also accommodated in the concave portion. Even if an axial force acts on the sliding bearing, the protrusion, the protrusion, and the protrusion engages with the concave portion, the concave portion, and the concave portion, so that the washer and the washer are not detached from the half bearing.

Sliding bearing

Half slide bearing

A valve assembly in which, even if a housing corrodes, application of a radially inward compression force to a heat-resistant filter can be suppressed. The valve assembly includes the housing having a gas path and a valve shaft hole, a valve having a valve shaft movably inserted in the valve shaft hole and also having a valve element connected to the valve shaft, and tubular heat-resistant filters installed between the inner peripheral surface of the valve shaft hole and the outer peripheral surface of the valve shaft and capturing dust in exhaust gas. The housing is made of cast iron. The valve assembly further has reinforcement collars installed between the inner peripheral surface of the valve shaft hole and the outer peripheral surfaces of the heat-resistant filters. The reinforcement collars have higher rigidity than the heat-resistant filters. At least the surfaces of the reinforcement collars are made of a high corrosion resistant material having higher corrosion resistance than the cast iron.

Valve assembly

A flow control valve in which corrosion is less likely to occur in the vicinity of a radial step portion in a gas passage of a housing and a method for manufacturing the same are provided. A flow control valve includes: a housing formed with a gas passage including a first cylinder member accommodating portion, a second cylinder member accommodating portion, and a radial step portion; a first cylinder member accommodated in the first cylinder member accommodating portion; a second cylinder member accommodated in the second cylinder member accommodating portion; and a valve body that is rotatably arranged inside the first cylinder member and the second cylinder member in the radial direction. The housing is formed of cast iron. At least surfaces of the first cylinder member and the second cylinder member are formed of a highly corrosion resistant material. At least one of a first axial end surface and a second axial end surface includes an opposing portion that opposes the radial step portion in the axial direction. A gas seal structure is arranged between the opposing portion and the radial step portion.
