PROBLEM TO BE SOLVED: To provide an intake manifold of outboard motor capable of realizing a reduction of noise and an enhancement of assembility, a reliability and a durability without increasing the number of part items and the number of assembling steps. SOLUTION: In the outboard motor in which a multi-cylinder engine is loaded and an intake manifold 21 for distributing a suction air to the respective cylinder of this engine is made of synthetic resin, an IAC valve 63 for adjusting an amount of suction air to the intake manifold 21 in the idling state is integrally mounted to a valve holder 66 through elastic bodies 64, 65 in a complete floating state. These IAC valve 63, elastic bodies 64, 65 and valve holder 66 integrally formed are mounted to the intake manifold 21. |
