constituting a portion on the upstream side in the flow direction of intake air, and a first downstream portion 41L and a cond downstream portion 41R connected to the
downstream side of the upstream portion. There is. A substantially plate-like first upper flange 43L is connected to the upper end surfaces of the three first cylindrical bodies 42L in the first downstream portion 41L. In the first upper flange 43L, three openings 44L penetrate in the thickness direction. A first groove 51L is provided between the openings 44L adjacent to each other on the upper end surface of the first upper flange 43L. A cond groove 51R having a configuration similar to that of the first groove 51L is also provided on the upper end surface of the cond upper flange 43R in the cond downstream portion 41R.
