Abstract
In a recirculation valve, a first support target portion receives a biasing force of a biasing member on a first stepped surface and moves to one side in an axial direction, such that a first opening is blocked. The first support target portion moves to the other side in the axial direction against a biasing force of the biasing member due to a negative pressure on a downstream side with respect to an upstream side, such that the first opening opens.
