Beschreibung
Zusammenfassung:	A recirculation valve includes a first supported portion that closes a first opening when a valve body biased by a biasing member is moved to one side in the axial direction, the first supported portion opens the first opening when the valve body 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 that on an upstream side, the valve body includes a first hole extending from an end portion on the other side in the axial direction to one side in the axial direction, and a valve body barrel portion includes a second hole that extends from a radially outward side thereof and reaches the first hole.
