Abstract: An object of a support structure for an intake manifold in accordance with the present invention is to reduce the number of parts and to improve the space efficiency. To achieve the object, the support structure is so configured that a surge tank 3 and a flange 4 are connected to each other by means of a stay member 23, by which the rigidity of the intake manifold 21 is enhanced, and EGR gas is introduced into the surge tank 3 via the stay member 23.

Abstract: There is disclosed an air cleaner of an engine for a vehicle. The air cleaner shaped by fitting upper and lower cases together includes an air intake unit inclined downwards so that a cylindrical part, provided at the top end of the air intake unit, for joining an air valve is disposed in a relatively lower position than the air intake unit. During a process of airtightly fitting the upper and lower cases, this arrangement restrains an engine overall height to a low value and prevents fluctuations in sectional area of the air intake unit which are due to reconstruction of the air intake unit to eliminate the difficulty caused particularly in a portion for joining the air valve to the air intake unit.
