<p>PROBLEM TO BE SOLVED: To provide a fixedly supporting device, capable of preventing vibration generation such as the resonance, etc., of a synthetic-resin-made manifold, to restrain the distortion or twist of the manifold at a minimum. SOLUTION: This device has inlet and outlet flange parts 17 and 15D connected to a surge part 11A and port parts 11B and 15B respectively. The inlet and outlet flange parts are joined to a throttle valve main body and the joining surface of the intake port part of an engine main body 100 respectively. A reinforcing member 40 is strided on the inlet flange part, and one or plural places other than the inlet flange part between a surge part and an engine main body, in a fixedly supporting device 300 to the engine main body of a synthetic resin-made manifold 1. The reinforcing member is composed of a supporting plate 40A, arranged in a horizontal attitude between the surged part and the throttle main body, and the engine main body, and a reinforcing plate 40B arranged in a direction nearly orthogonal to the supporting plate; and is joined to the joined surface 17A of the throttle valve main body of the inlet flange part.</p> |
