PROBLEM TO BE SOLVED: To apply a stack type air suction duct to left and right steering wheel vehicles and recline the seat backs of a driver's seat and a front-seat passenger's seat backward in a large amount by arranging the stack type air suction duct in a recessed portion extending in the vertical direction at the center of a rear wall part between the driver's a seat and the front-seat passenger's seat whose seat backs can be reclined backward. SOLUTION: A recessed portion 30 for arranging a rising part 32 of a stack type air suction duct 31 is formed at the center part of a rear wall part 25. The rear wall part 25 projects each of a driver's seat 22 and a front-seat passenger's seat 23 to the rear side of a vehicle on the rear side of each of them. Namely, space at the inside of a cab 20 on the rear side of each of the driver's seat 22 and the front-seat passenger' seat 23 is further spread to the rear side of the vehicle by a thickness difference of the rear wall part 25 and a glass window 29. Therefore, each of the seat backs 21 of the driver's seat 22 and the front-seat passenger' seat 23 can be reclined to the rear side of the vehicle as occasion demands and the reclining angle can be easily increased. Both of a driver and a front-seat passenger can easily take rest as necessary even if a simple frame bed is not installed. |
