PROBLEM TO BE SOLVED: To appropriately detect stuffiness and eliminate it without being affected by changed in a seating attitude or causing complication, etc., in a constitution. SOLUTION: This seat ventilation structure 10 comprises both a stuffiness detecting device 12 comprising right and left detecting electrodes 20-R and 20-L arranged in parallel at an interval in a seat cushion and utilizing the principle of a capacitance-type approximately switch and an air blowing device 14 comprising right and left ventilation path groups 44-R and 44-L formed of a plurality of flexible tubes 42 arranged in parallel on the detecting electrodes in at least the equivalent areas as those of the detecting electrodes. By actuation control over the blowing device 14 by the stuffiness detecting device 12 when the stuffiness detecting device 12 detects and determines the occurrence of stuffiness between a human body on a seat surface and a section in contact with the human body on the basis of the comparison between relative output values of the detecting electrodes 20-R and 20-L and a predetermined set value, it is possible to supply air between the human body and the section in contact with the human body. |
