PROBLEM TO BE SOLVED: To provide a technique capable of assisting pedal work.SOLUTION: An air bag 26 is disposed on a seat cushion 12 of a vehicular seat 10. In the air bag 26, a first bag body 30 disposed on a vehicle rear side and a second bag body 32 disposed on a vehicle front side are communicated, and flowing of air in the first bag body to the second bag body is allowed, but only when air pressure in the second bag body becomes equal to or more of set pressure, flowing of air in the second bag body to the first bag body is allowed. Therefore, when a driver steps a brake pedal 70 and the like by a foot, the second bag body disposed on the vehicle front side of the seat cushion, is pressed by the driver's foot. At the time, the air pressure in the second bag body exceeds the set pressure, distribution of air from the second bag body to the first bag body is allowed, the second bag body is shrunk and the first bag body is inflated. Thereby, a joint between a calf and thigh of the driver moves downward, and a hip part of the driver moves upward, so that a step amount of the brake pedal and the like is increased, and pedal work is assisted. |
