Abstract
An intake manifold made of a synthetic resin includes a surge tank, and a plurality of intake pipes disposed in parallel to one another and each having a rising pipe portion which is connected to a lower portion of the surge tank and extends upwards. A space is defined between the surge tank and each of the rising pipe portions, as viewed sideways. In order to enable an increase in volume of the surge tank, while avoiding an increase in size of the intake manifold, the surge tank ( ) includes a main tank portion ( ) extending in a direction ( ) of arrangement of the intake pipes ( A to D) and opposed to the rising pipe portions ( A to D) of the intake pipes ( A to D), and a sideways-bulged portion ( ) which is bulged from an intermediate portion of the main tank portion ( ) as viewed in the arrangement direction ( ) and is interposed between a pair of rising pipe portions ( B, C) disposed at the intermediate portion as viewed in the arrangement direction . Inner ends of a pair of the spaces ( ) defined respectively between the rising pipe portions ( A to D) and the main tank portion ( ) on opposite sides of the sideways-bulged portion ( ) are closed by opposite sidewalls of the sideways-bulged portion ( ).
