In this case, the wire 53 is arranged on the side edge 11a1 portion of the folding portion 11a from the viewpoint of improving the contact performance with the first side member 14 in the hood deployed state as described above. The rigidity of the wire 53 acts to cause the side edge 11a1 portion to protrude outward in the hood retracted state, and is a factor that impairs the aesthetics of the hood device 10 in the hood retracted state. Therefore, in order to ensure good aesthetics in the hood storage state, it is necessary to pull the side edge 11a1 portion inward in the folding direction and prevent it from protruding outward. In order to satisfy such a requirement, the hood side edge retracting means Z described below is provided in the folding portion 11a portion by applying the present invention to this embodiment.
[0028]

That is, the band 51 is inserted into a holding bag 52 attached in the width direction so as to straddle both side edges 11a1 and 11a1 on the back side (vehicle compartment side) of the folded portion 11a of the hood 11. . Then, both end portions 51a and 51a of the band 51 are drawn out from the both end portions 52a and 52a of the holding bag 52, respectively, and then bypass the outside of the first link 20 and the side edges 11a1 of the folding portion 11a. It is fixed to. The retracting action of the side edge 11a1 of the folded portion 11a by the hood side edge retracting means Z will be described later.
[0029]
In FIG. 4, reference numeral 9 denotes a lock mechanism provided at the other end 14 b of each of the first bending members 14, 14, and the lock mechanism 9 is in a hood deployed state as shown in FIG. It is fixed to each lock receiving member 26, 26 provided on the front header 5 side. Further, the lock mechanisms 9 and 9 are fixed to lock receiving members 27 and 27 provided on the side of the vehicle compartment rear portion 6B as shown in FIG. In FIG. 4, reference numeral 28 denotes an operation handle provided at a substantially central portion in the vehicle width direction of the lateral member 19.
[0030]
Next, the operation of the hood device 10 will be described.
[0031]
At the time of unfolding operation of the hood device 10 The unfolding operation of the hood device 10 is performed from the hood storage state shown in FIG. That is, in the state where the hood device 10 is stored, first, the lock mechanisms 9 and 9 are unlocked, and then the operating handle 28 is gripped to apply an operating force obliquely upward to the lateral member 19. The hood bone mechanism 12 is deployed from its retracted state. Finally, by fixing the lock mechanisms 9 and 9 to the lock receiving members 26 and 26, a hood deployed state as shown in FIGS. 1 and 4 is obtained, and the operation is completed. And in this hood deployment state, the said folding part 11a is made into the tension state.
[0032]
At the time of storing operation of the hood device 10 The storing operation of the hood device 10 is performed from the hood deployment state shown in FIG. That is, first, the lock mechanisms 9 and 9 are detached from the lock receiving members 26 and 26, respectively. Thereafter, the operating handle 28 is used to apply an operating force to the lateral member 19 toward the rear side of the vehicle body to gradually bend the hood bone mechanism 12 from the deployed state, and finally, as shown in FIG. The lock mechanisms 9 and 9 are fixed to the lock receiving members 27 and 27 to complete.
[0033]
When the hood device 10 is stored in the hood, the foldable portion 11a of the hood 11 is folded inward. When the foldable portion 11a is folded, the hood side edge retracting means Z functions effectively, and the folded portion It is possible to surely prevent the side edge 11a1 portion of 11a from protruding to the outside, and to enhance the aesthetics in the hood storage state. That is, in the hood side edge retracting means Z, both end portions 51a, 51a of the band 51 disposed between both side edges 11a1, 11a1 of the folding portion 11a bypass the outside of the first link 20. Then, it is fixed to the both side edges 11a1, 11a1, respectively. On the other hand, the relative position of the first link 20 with respect to the side member 13 differs between the hood deployed state shown in FIG. 5 and the hood retracted state shown in FIG. 9, and the relative interval in the hood retracted state is the relative interval in the hood deployed state . More to expand. Therefore, as described above, when the end portion 51a of the band 51 is fixed to the side edge 11a1 of the folding portion 11a while bypassing the outside of the first link 20, the distance between the first link 20 and the side member 13 is increased. 8 and 9, when the hood is retracted, the side edges 11a1 and 11a1 of the folding part 11a are pulled inward in the folding direction by the band 51, and the overhang to the outside is surely prevented. As a result, the aesthetics are made good.
