  However, the hydraulic cylinder is fixed to the front wall, and the hydraulic cylinder moves left and right together with the beam. Therefore, the length of the hydraulic pipe needs to be sufficiently long in consideration of the amount of movement of the hydraulic cylinder. Also, since the extension direction of the hydraulic pipe changes when the beam moves, it is necessary to provide a caterpillar to prevent the hydraulic pipe from interfering with other members and to install the hydraulic pipe in the caterpillar. is there. Therefore, there is a demand for a simpler structure for the wing type vehicle luggage compartment.

  In order to solve the above-mentioned problems, the present invention is a wing type vehicle luggage compartment having a configuration as described in each claim. According to one aspect, the present invention includes a front wall, a rear wall opposite the front wall, a beam extending between the front wall and the rear wall, a pair of wings rotatably attached to the beam, and each wing. Each of the hydraulic cylinders that rotate in the vertical direction with respect to the beam, a hydraulic unit that generates hydraulic pressure from electric power, and a hydraulic pipe that connects the hydraulic unit and each hydraulic cylinder. The beam has a front portion attached to the front wall so as to be movable in the left-right direction, and a rear portion attached to the rear wall so as to be movable in the left-right direction. A hydraulic unit is attached to the beam, and the hydraulic unit, each hydraulic pipe, and each hydraulic cylinder move together with the beam.

  Therefore, when the beam is moved to the left and right, the hydraulic pipe moves together with the beam. Therefore, it is not necessary to increase the length of the hydraulic pipe in consideration of the movement amount of the beam. Therefore, the length of the hydraulic pipe can be shortened compared to the conventional structure. In addition, since the extension direction of the hydraulic pipe does not change greatly even if the beam moves, the hydraulic pipe hardly interferes with other members. Therefore, the caterpillar etc. which suppress that a hydraulic pipe interferes with other members are unnecessary.

  When the right wing 6 is rotated upward from the closed position in FIG. 6 where the left and right wings 5 and 6 are rotated downward, the right wing 6 moves to the open position indicated by the phantom line in FIG. The right wall upper part 6 b is in a folded state and is located on the left side of the beam 4. When the beam 4 is moved in the left direction, the beam 4 and the wings 5 and 6 are moved in the left direction. As a result, the entire upper part of the cargo compartment 1 is opened.

  When the left and right wings 5 and 6 are rotated upward from the closed position in FIG. 6, the left wing 5 moves to the open position indicated by the phantom line in FIG. 8. The left wall upper part 5 b is in a folded state and is located on the right side of the beam 4. When the beam 4 is moved in the right direction, the beam 4 and the wings 5 and 6 are moved in the left direction. As a result, the entire upper part of the cargo compartment 1 is opened.

  When the left and right wings 5 and 6 are rotated upward from the closed position in FIG. 6 with the locking device 15 in the locked state, the tips of the wings 5 and 6 are positioned outward from the cargo compartment 1. As a result, a rain guard can be formed by the wings 5 and 6. The same effect can be obtained by rotating one of the left and right wings 5 and 6 from the closed position to the open position.

  As described above, the luggage compartment 1 includes a front wall 2, a rear wall 3 facing the front wall 2, a beam 4 extending between the front wall 2 and the rear wall 3, as shown in FIGS.

The beam 4 has a front part attached to the front wall 2 so as to be movable in the left-right direction and a rear part attached to the rear wall 3 so as to be movable in the left-right direction. A hydraulic unit 8 is attached to the beam 4, and the hydraulic unit 8, each hydraulic pipe 17, and each hydraulic cylinder 12 move together with the beam 4.

  Therefore, when the beam 4 is moved to the left and right, the hydraulic pipe 17 moves together with the beam 4, so that it is not necessary to increase the length of the hydraulic pipe 17 in consideration of the movement of the beam 4. Therefore, the length of the hydraulic pipe 17 can be shortened compared with the conventional structure. Further, since the extending direction of the hydraulic pipe 17 does not change greatly even if the beam 4 moves, the hydraulic pipe 17 hardly interferes with other members. Therefore, a caterpillar or the like for suppressing the hydraulic pipe 17 from interfering with other members is unnecessary.

  As shown in FIG. 2, a bracket 7 extending downward from the front part is provided at the front part of the beam 4. A hydraulic unit 8 is attached to the bracket 7, and the hydraulic unit 8 is positioned in front of the front wall 2. Accordingly, the hydraulic unit 8 is suspended from the beam 4 by the bracket 7. Therefore, the hydraulic unit 8 can be attached to the beam 4 more stably than when the hydraulic unit 8 is positioned above the beam 4. The hydraulic unit 8 is located in front of the front wall 2. Therefore, the hydraulic unit 8 is located outside the cargo compartment 1 and does not narrow the space in the cargo compartment.

  The present invention is not limited to the above-described embodiment, and may be the following form. For example, the hydraulic unit 8 may be attached to the beam 4 via the bracket 7 or may be attached to the beam 4 without going through the bracket 7.

  The hydraulic unit 8 may be attached to the front end portion of the beam 4, or may be attached to the center portion or the rear portion of the beam 4. The hydraulic unit 8 may be located outside the cargo compartment 1 or inside the cargo compartment 1.
