PROBLEM TO BE SOLVED: To obtain the sufficient real intake passage length with simple structure when obtaining the dynamic supercharging effect of the intake air. SOLUTION: Intake pipes 70 and 71 communicated with a downstream side and an upstream side of a throttle body 15 are provided with bulkheads 72 and 73 crossing the axis of a throttle valve 14 and for parting inside of the intake pipes 70 and 71 along the flow of the intake air. Each partitioning plate 74 communicated with the bulkheads 72 and 73 is suspended in both surfaces of the throttle valve 14 so as to separately form a pair of intake passages 75a and 75b continued over from the upstream side to the downstream side of the throttle valve 14 in the common intake pipes 70 and 71. These intake passages 75a and 75b are separately communicated with intake chambers 7a and 7b of each cylinder group through passages 13a and 13b.
