Provision of a Westgate valve capable of reducing costs by compiling mounting plates and reducing total weight.In the west gate valve (50), the pivoting shaft 58 is offset from the mounting plate 52 supporting the valve body 56 to the valve body 56 and extends in a direction substantially orthogonal to the central axis (o) of the valve body 56, and the whole of which is formed into an L shape in the plan view The rotary shaft body 58a is fixed to the side of the mounting plate 56 by solid phase bonding.The reduction of the cost of the valve (50) and the reduction in the total weight are achieved by compactness of the mounting plate (56), and the restriction of the exhaust gas flow path (9) equipped with the bypass passage (10) is also relaxed.
