摘要：<p>PROBLEM TO BE SOLVED: To improve intake distribution capability from an air cleaner by forming the opening edges of respective intake lines toward the inside of a surge tank into an arc shape and making the radius of the arc surface small for an intake line which overlaps with an intake inlet among the respective intake pipes, and large for an intake pipe which does not overlap. SOLUTION: The intake air flowing into a surge tank 3 from an intake inlet 9a is distributed to intake lines 4, 5 and 6 led to respective cylinders in the surge tank 3. The radii of arc surfaces 4a', 5a' and 6a' of an opening edge in the connected parts of intake lines 4, 5 and 6 to the surge tank 3 parts 4a, 5a and 6a are formed into a small R2 for the second cylinder intake line 5 which overlaps with the intake inlet 9a among the intake lines 4, 5 and 6, and a large R1 for the first and third cylinder intake lines 4, 6 which do not overlap. It is thus possible to make flow resistance large for the second cylinder intake line 5, and small for the first and third cylinder lines 4, 6.</p>
