<p>PROBLEM TO BE SOLVED: To prevent the freezing of a negative pressure take-out part without changing the pressure of an intake pipe. SOLUTION: A mounting plate 2 connected to the upstream parts of an intake passage is connected to a surge tank 4 through a cylindrical air connector 3. Distribution pipes 5A, 5B, 5C, 5D, 5E, 5F are connected to the surge tank 4, and each terminal part of each distribution pipe is connected to an intake port plate 6. The intake port plate 6 is connected to the combustion chamber of an engine through an intake port. The backmost distribution pipe 5F in a direction that a vehicle travels is formed by being projected to the rear of the direction that the vehicle travels so as to be projected further than the belly part 3A of the air connector 3, and a remaining part is formed by the distribution pipe 5F and the belly part 3A of the air connector 3. In the remaining part, negative pressure take-out parts 10, 11 are formed in the belly part 3A, and the negative pressure removing part 10 is connected to a presser sensor 13 through a connecting pipe 12.</p> |
