  The rear end portion of the main board 36m and the free end portion of the sub board 36s are connected so as to be bendable by a hinge portion 38 including a hinge pin 37, as in the previous embodiment.

  Pulleys P2 and P2 are provided on both sides of the base end portion of the above-mentioned sub board 36s, and pulley shafts 63 and 63 of these pulleys P2 and P2 are pivotally supported on the body side such as the cargo compartment floor 4 or the like.

A wire W4 is stretched between the pulley P1 on the seat back 33B side and the pulley P2 on the cargo compartment floor 4 side.
The operation of the rear luggage compartment structure of the vehicle configured as described above will be described below.
When only one of the two levers 50 and 51 shown in FIG. 15 is pulled, the lock lever 49 is removed via the wire W1, and the other lock lever 47 maintains the state shown by the solid line in FIG. Therefore, the seat back 33B in the use state shown by the solid line in FIG. 14 can be laid down on the seat cushion 33C as shown by the phantom line in FIG. Since non-interlocking is selected, the luggage compartment board 36 is positioned above the luggage compartment floor 4 without moving upward.

  When both of the two levers 50 and 51 shown in FIG. 15 are pulled simultaneously, the lock lever 49 is disengaged, and the other lock lever 47 is connected to the recess 43a of the disc 43 and the pulley as shown by the phantom line in FIG. When the seat back 33B, which is simultaneously engaged with the concave portion 44 of P1 and operated in the direction shown by the solid line in FIG. 14, is moved forward in the direction of the arrow in FIG. 14, the pulley P1 constituting the board interlocking mechanism 54 is moved in the direction of the arrow in FIG. When the wire W4 is pulled forward, the pulley P2 rotates in the direction of the arrow in FIG. 14, so that the load is linked to the folding operation of the seat back 33B as indicated by the phantom line in FIG. The chamber board 36 can be moved upward.

A flat cargo room surface is formed.

  When the seat back 33B is returned to the use state after the folding operation of the seat back 33B shown by the phantom line in FIG. 14, the interlocking operation of the both 33B and 36 by the board interlocking mechanism 54 can be canceled. That is, when the lock lever 47 is operated to the solid line state of FIG. 16 by operating the lever 51 of the selection mechanism 55, only the seat back 33B can be returned from the folded state to the used state, and the luggage compartment board 36 is virtually shown in FIG. It can be held under the upward movement state indicated by the line.

  On the other hand, when the seat back 33B is returned to the use state after the folding operation of the seat back 33B shown by the phantom line in FIG. 14, the luggage compartment board 36 can be moved in conjunction with the lower side. That is, if the lock lever 47 is maintained in the phantom line state of FIG. 16 by operating the lever 51 of the selection mechanism 55, when the seat back 33B is returned from the folded state to the use state, the boards 33B and 36 are interlocked by the board interlocking mechanism 54. Therefore, the luggage compartment board 36 can be moved downward.

  Further, after the cargo compartment board 36 indicated by the phantom line in FIG. 14 is moved upward, when the cargo compartment board 36 is moved downward, the lock lever 47 of FIG. When the operation is performed in the solid line state, the interlocking operation of the both 33B and 36 is released, and only the cargo compartment board 36 can be operated from the upper position to the lower position, and the seat back 33B can be held in the lying down state.

  In short, the board interlocking mechanism 54 can be replaced with the gear coupling structure shown in the first embodiment, and a board interlocking mechanism using the pulleys P1 and P2 and the wires W4 shown in FIGS. Since the operation and effect are exhibited, the same reference numerals are given to the same portions in FIGS. 13 to 17 as in the previous drawings, and detailed description thereof is omitted.

  Here, instead of the structure shown in FIG. 14, the structure shown in FIG. 18 may be adopted. That is, the luggage compartment floor 4 at the portion where the pulley P2 is disposed is formed with a recess 4a in a range that does not interfere with the wire W4, and the pulley P2 is disposed corresponding to the recess 4a, so that the main at the downward movement position can be obtained. A structure in which the lower surfaces of the board 36m and the sub board 36s are in contact with the upper surface of the cargo floor 4 may be employed.

With this configuration, when a load is placed on the upper surface of the cargo compartment board 36 at the downward movement position, the load urged by the cargo compartment board 36 can be received by the cargo compartment floor 4. It is possible to improve the performance.
