When 0 is at the frontmost full storage position, as shown in FIG. 22, each switch piece of the intermediate position detection switch LS1 and the total lowering detection switch LS2 is in contact with the NC contact,
The switch piece of the all-storage detection switch LS3 is in contact with the NO contact. At this time, in the parking state, the parking switch 77 is turned on, the back door is fully closed, and the back door full open switch 8
1 is on.

That is, when the back door is not closed, the drive motor 50 becomes inoperable, and when the vehicle is not in the parking state, the drive motor 50 is inoperable, so the roof carrier device is inadvertently operated. It is possible to increase the safety. When the moving frame 40 contacts the switch piece of the in-vehicle switch 78 with the contact on the descending side in order to load and unload luggage, the drive motor 50 rotates in the normal direction, and the drive gear 52 rotates via the speed reduction mechanism 51, and the geared state is reached. The cable 53 is fed out backward. As a result, the joint member 45 moves rearward,
The guide roller 32 relatively rolls in the guide groove 41, the guide roller 42 rolls in the guide groove 31, and the moving frame 40 moves rearward. At this time, the roller 48 for controlling the backlash on the front frame side and the fixed frame 2
The roller 38 for rattling provided at the rear end portion 0 rolls while contacting the fixed frame 20 and the moving frame 40 from the side of the vehicle, so that the moving frame 40 does not rattle to the side of the vehicle.

When the moving frame 40 moves to the rear intermediate position and the guide roller 32 relatively moves to the front end portion 41a of the guide groove 41, the switch piece of the intermediate position detecting switch LS1 comes into contact with the NO contact to cause the relay. The coil R4 of No. 4 is de-energized, the a contact S4 is opened, the coil R2 is de-energized, the drive motor 50 stops rotating, and the moving frame 40 stops moving. Next, when the operator touches the touch sensor 74, the touch sensor 74 is closed, the coil R8 of the relay 8 is energized, and the a contact S8 is closed,
The drive motor 50 restarts. When the drive motor 50 is activated, the guide roller 42 is relatively raised by the guide groove 31, while the guide roller 32 is relatively lowered by the guide groove 41. Therefore, the moving frame 40 is rotated while moving rearward, and the caster is rotated. 46 and 47 reach the rear surface of the vehicle body and can roll on the rear surface.

At this time, since the moving frame 40 rotates around the pivot 72 of the cable end grip 71 fixed to the geared cable 53, no bending force is applied to the geared cable 53, and the geared cable 53 is guided in the guide groove 34. It moves smoothly and the moving frame 40 also moves smoothly. Further, when the frame body 44 moves backward,
The hood body 44 gradually tilts downward, and finally, as shown in FIG.
As shown in, the vehicle moves to the loading / unloading position, which is largely inclined downward at the rear position of the vehicle. When the front frame 43 moves to the loading / unloading position, the switch piece of the all-lowering detection switch LS2 contacts the NO contact, and the a contact S
7, the coil R8 is not energized and the a contact S
8 is opened, and the drive motor 50 stops rotating.

When the frame main body 44 is lowered to the loading / unloading position, the operator can operate it while paying attention to the people and things around the front frame 43 which is being lowered, and the safety can be improved. . When the front frame 43 is moved to the loading / unloading position, the switch pieces of the all-storage detection switch LS3 are in contact with the NC contact, the coil R5 is energized, and the a contact S5 is closed. When the switch piece of the vehicle-mounted switch 78 is brought into contact with the contact on the storage side, the coil R3 is energized, the a contact S3 is closed, and the drive motor 50 rotates in the reverse direction.

When the drive motor 50 rotates in the reverse direction, the geared cable 53 comes forward by the drive gear 52, and the moving frame 40 moves forward. When the moving frame 40 moves forward, the guide roller 42 is guided by the guide groove 31 and relatively descends, while the guide roller 42 is guided by the guide groove 41 and relatively moves upward. It rotates in the direction in which its inclination becomes gentle. Further, the casters 46 and 47 are separated from the rear surface of the vehicle. Also at this time, the pivot portion 7 of the cable end grip 71 fixed to the geared cable 53
Since the moving frame 40 rotates about two times, no bending force is applied to the geared cable 53, and the geared cable 53 smoothly moves in the guide groove 34, and the moving frame 40
Also moves smoothly. Further, when the moving frame 40 moves forward to the full storage position, the full storage detection switch L
The switch piece of S3 contacts the NO contact, the coil R5 is no longer energized, the a contact S5 is opened, and the coil R3 is no longer energized. Then, 1 second after this, the drive motor 50 stops rotating. The rotation of the drive motor 50 was stopped after one second because of the locking operation of the moving frame 40.

When the front frame 43 is moving rearward, the actuator 82 locks the back door locking device via the control unit 75 to make the back door inoperable. It is possible to prevent mutual interference with and improve safety. Next, the movable frame 4 at the frontmost position, that is, all the storage positions
The lock operation of 0 will be described.

As shown in FIGS. 13, 16 and 17, when the geared cable 53 pulls the lock slider 64 forward through the cable end grip 67 before the moving frame 40 moves to the full storage position, The cam portion 65 pushes the inclined edge 63 forward, and the front frame 43 moves forward via the lock arm 61. At this time, the lock roller 62 rolls on the lower wall surface of both groove walls of the guide groove 31. When the front frame 43 is pulled by the geared cable 53 and moves forward, the moving frame 40 eventually moves to all storage positions. Before and after, the lock roller 62 is located above the lock groove 36. Further, when the drive motor 50 rotates for a certain period of time (1 second) and the lock slider 64 is pulled further forward by the geared cable 53, FIG.
As shown in FIG. 6, the cam portion 65 of the lock slider 64 resists the biasing force of the eject pin 37a and the lock arm 6
The inclined edge 63 of No. 1 is pushed in, the lock arm 61 swings, and the lock roller 62 is fitted into the lock groove 36, as shown in FIG. The frame 40 is locked at all storage positions. In the locked state, the lock arm 61 elastically abuts the lock slider 64 by the upward biasing force of the eject pin 37,
As a result, rattling of the moving frame 40 can be suppressed. In the locked state shown in FIG. 15, when the drive motor 50 rotates in the reverse direction and the geared cable 53 moves the lock slider 64 rearward via the cable end grip 67, the cam portion 65 of the lock slider 64 tilts the lock arm 61. Away from the rim 63, the lock arm 61
Is rocked by the urging force of the eject pin 37, the lock roller 62 is disengaged from the lock groove 36, and is unlocked. Further, the rear surface portion of the lock slider 64 contacts the stepped surface of the front frame 43, Four
3 will be pushed backwards. This allows the moving frame 40 to move backward.
