Abstract
In a variable air induction apparatus, a valve element is switched between one side to open a first air intake passage and close a second air intake passage, and the other side to open the second air intake passage and to close the first air intake passage. The first air intake passage and the second air intake passage have lengths different from each other. The valve element is fixed on a shaft member to rotate integrally with the shaft. A driving device applies a driving force to rotate the shaft member. An urging device urges the shaft member to rotate the valve element to be switched to any one of the one side and the other side.
