摘要： A vehicle seat includes: a chamber in which at least a seat-front-surface side is covered with a pad and which circulates the air blown from a front surface of a seat through the pad; a fan configured to send air into the chamber; and a support body which supports the chamber so as to be able to sink in an acting direction of a load applied to the surface of the seat. The chamber includes a first region and a second region, and the first region and the second region are configured to allow subduction of the chamber independently of each other.
