wherein the through hole is located in such a position that ranges covered respectively by the through hole and by the support portion in a direction perpendicular to a lateral direction overlap each other.

8. The vehicle seat according to claim 1 , further comprising a seating sensor attached to the support member,

wherein the support member comprises a plate having a through hole configured to allow the duct to be disposed therethrough, the through hole being provided in a position other than a portion of the plate to which the seating sensor is attached.

9. The vehicle seat according to claim 8 , wherein the seating sensor is located in such a position that ranges covered respectively by the seating sensor and by the through hole in a direction perpendicular to a lateral direction overlap each other.

10. The vehicle seat according to claim 1 , further comprising a plurality of harnesses routed on the opposite side of the support member,

wherein the plurality of harnesses are so located as to detour around the blower and the duct.

11. The vehicle seat according to claim 1 , further comprising a pad member having air vents formed in a surface thereof on the occupant side and an air passage connected to the air vents,

wherein the second end of the duct is connected to the air passage.
