うに構成される。 As shown in Figure 2, the cab of a truck has a driver's seat 3 consisting of a seat 1 and a backrest 2, an auxiliary seat 6 consisting of a seat 4 and a backrest 5, and a seat located behind these seats. It is equipped with a bed 7. The rear part of the bed 7 is defined by a rear wall 12 having a window 10.
Headrests 8 and 9 are attached to the upper end surfaces of each backrest portion 2 and 5.
is installed. The auxiliary seat 6 is configured so that when the backrest portion 5 is tilted forward, it presents a flat surface approximately at the same height as the bed 7.

キヤブの床部３０は補助席６の後側から一段高

る。 In the case of rest, as shown in FIGS. 1 and 3, the backrest 5 of the auxiliary seat 6 is folded forward, the divided body 7a of the bed 7 is pulled up around the hinge 26, and the hook 24 is attached to the lower end of the band 22. When the split body 7a is engaged with the split body 7a, the divided body 7a is held at a desired inclined position, and a resting floor surface that is long and inclined in the front and back direction is formed. Therefore,
The occupant can use the divided body 7a as a backrest, place the lower half of his body on the backrest part 5, and stretch his legs straight.
