<p>PROBLEM TO BE SOLVED: To prevent generation of noise due to resonance of an air suction chamber by forming the air suction chamber of a first chamber integrally forming a manifold and a second chamber connecting an air suction pipe and sandwiching and joining a reinforcing plate between flange surfaces provided on opening parts of both of the chambers. SOLUTION: An air suction chamber is divided into a chamber 2 and a chamber 3, and a reinforcing plate 6 is sandwiched by their flanges 4, 5. Air suction manifolds 7 in the same number of cylinders of an engine are provided on the chamber 2, and an air suction pipe 8 is connected to one end of the chamber 3. The reinforcing plate 6 functions to mix suction air supplied from the air suction pipe 8 while partitioning chambers 2a, 3a, to disperse it so as to uniformly supply it to each of the air suction manifolds 7 and to reinforce the air suction chamber. That is, it is formed in a lattice shape by having a frame part 6a, a vertical reinforcing plate 6b and a lateral reinforcing plate 6c and opening a window 6d between them.</p> |
