Abstract: A cooling structure for vehicle high-voltage electric parts includes an air inlet passage 26 having an air inlet port 32 which is disposed higher than a seat cushion 6 of a rear seat 7 so as to supply air from a passenger compartment 9 to a battery unit 21, an inverter unit 22 and a DC-DC converter unit 23 and a cooling fan 30 which causes cooling air to flow into the air inlet passage 26. An opening portion 35 from which air is taken into the air inlet passage 26 is formed inside a side seatback 4 which is placed transversely outward of a main seatback 5 of the rear seat 7.

Abstract: A seat main body is mounted on a seat mount base on a vehicle body floor through left and right seat rails. The seat mount base includes left and right side members and a connection member connecting substantially central portions of the side members to each other. The seat rails each include a lower rail and an upper rail. Force sensors are disposed between the side members and the corresponding lower rails. The upper rails are secured to the seat main body. A central region of the connection member, located substantially in a center in a seat width direction, protrudes toward the front compared to joining portions where the connection member is joined to the left and right side members. A space opening toward the rear is formed between the joining portions.
