PURPOSE: A structure for fixing an intake manifold of an engine is provided to improve the structural stability of the intake manifold and the durability, and to decrease vibration and noise by firmly fixing and mounting the throttle body installation portion of the intake manifold integrally formed with the surge tank with a boss and an assembling bolt. CONSTITUTION: An intake manifold(1) is integrally connected to a throttle body installation flange(3), and a boss part(7) is integrally formed in the throttle body installation flange and combined with an engine block by an assembling bolt. The intake manifold is integrally formed with a surge tank(9), and the throttle body installation flange is formed in the inlet of the surge tank to mount a throttle body. The throttle body is mounted in the throttle body installation flange, and a boss protruded downward is fixed firmly to the side of the transmission installation flange by the assembling bolt. The intake manifold is mounted stably to the engine.
