Abstract:
1. An air intake control valve, comprising: a body configured to be mounted in an inner portion of a surge tank of a multi-cylinder internal combustion engine to divide the inner portion of the surge tank into two portions, the body serving as a divided surface to divide the inner portion of the surge tank into the two portions when the air intake control valve is mounted to the surge tank; a valve element operated to rotate for opening and closing a fluid passage formed at the body when the air intake control valve is mounted to the surge tank; a seal member configured to seal between a sealed surface of the surge tank and an outer periphery of the body, the seal member including a seal portion constituted by two contact portions that make contact with the sealed surface in a state in which the air intake control valve is mounted to the surge tank and the two contact portions extend in directions opposite from each other relative to the divided surface; and the air intake control valve being configured so that when the air intake control valve is mounted to the surge tank and one of the contact portions faces one of the two portions of the surge tank having a higher air pressure than the other one of the two portions of the surge tank, the contact portion that faces the one portion of the surge tank having the higher air pressure than the other one of the two portions of the surge tank is pressed against the sealed surface by the higher air pressure.
