The winding tension Fr is set so that the rear end of the front tonneau cover 20 and the front end of the rear tonneau cover 30 move up and down along the slide rail 41 in conjunction with the opening / closing operation of the back door 4.

Thereby, the cargo compartment T front part is covered with the front part tonneau cover 20, and the cargo compartment T rear part is covered with the rear part tonneau cover 30, Therefore The whole cargo compartment T can be covered with the tonneau cover apparatus 10. FIG. Also, the rear end of the front tonneau cover 20 and the front end of the rear tonneau cover 30 are moved up and down in conjunction with the opening / closing operation of the back door 4 by the winding tension Ff of the front tonneau cover 20 and the winding tension Fr of the rear tonneau cover 30. be able to.
For this reason, the gap between the rear end of the front tonneau cover 20 and the back door 4 can be covered with the rear tonneau cover 30. Further, the front tonneau cover 20 and the rear tonneau cover 30 are moved up and down in conjunction with the opening / closing operation of the back door 4 only by the winding tensions Ff and Fr of the tonneau cover device 10 without providing a connecting member or an urging means. be able to.
Therefore, in the tonneau cover device 10 for a vehicle installed in a substantially horizontal unfolded state at a position above the luggage compartment T at the rear of the vehicle body, the rear tonneau cover 30 defines a gap formed between the back door 4 behind the front tonneau cover 20. The tonneau cover device 10 can be lifted upward in conjunction with the opening / closing operation of the back door 4 without setting an extra connecting member or the like.

In this embodiment, when the back door 4 is opened, the first component force F1 that is the component force of the winding tension Ff of the front tonneau cover 20 is the second component component of the winding tension Fr of the rear tonneau cover 30. It is set to be larger than the component force F2.
As a result, when the back door 4 is opened, the upward first component force F1 is larger than the downward second component force F2, so that the rear end of the front tonneau cover 20 and the front end of the rear tonneau cover 30 open the back door 4. In conjunction with the operation, it moves upward along the slide rail 41.
For this reason, it is possible to follow and move the rear end of the front tonneau cover 20 and the front end of the rear tonneau cover 30 upward simply by opening the back door 4 upward.
Therefore, in conjunction with the opening operation of the back door 4, the opening portion TO (see FIG. 10) behind the tonneau cover device 10 can be reliably expanded.

In this embodiment, the first component force F1 of the front tonneau cover 20 is set to be smaller than the second component force F2 of the rear tonneau cover 30 when the back door 4 is closed.
Thus, when the back door 4 is closed, the upward first component force F1 is smaller than the downward second component force F2, so that the rear end of the front tonneau cover 20 and the front end of the rear tonneau cover 30 are closed by the back door 4. It moves downward along the slide rail 41 in conjunction with the operation.
For this reason, it is possible to move the rear end of the front tonneau cover 20 and the front end of the rear tonneau cover 30 downward by simply closing the back door 4 downward.
Therefore, in conjunction with the closing operation of the back door 4, the opening TO at the rear of the tonneau cover device 10 can be reliably closed and the cargo compartment T can be completely covered.

Moreover, in this embodiment, the latch holding | maintenance part 42 which hold | maintains the substantially horizontal expansion | deployment state of the front part tonneau cover 20 and the rear part tonneau cover 30 is provided.
By providing the latch holding portion 42, the substantially horizontal unfolded state of the front tonneau cover 20 and the rear tonneau cover 30 is securely held.
For this reason, the positions of the front tonneau cover 20 and the rear tonneau cover 30 that move up and down are reliably deployed by the latching holding portion 42 by the balance between the winding tension Ff of the front tonneau cover 20 and the winding tension Fr of the rear tonneau cover 30. Therefore, the unfolded state of the front tonneau cover 20 and the rear tonneau cover 30 can be reliably retained.
Accordingly, the unfolded state of the front tonneau cover 20 and the rear tonneau cover 30 is always stable, and the tonneau cover device 10 does not flutter in the vertical direction when the vehicle is traveling.

In this embodiment, the rear tonneau cover 30 is configured to be retractable.
As a result, only the rear tonneau cover 30 can be stored and only the front tonneau cover 20 can be unfolded (see FIG. 12).
For this reason, the front tonneau cover 20 alone can cover the upper part of the luggage compartment T, and a gap is intentionally set between the rear end of the front tonneau cover 20 and the back door 4, and this gap is utilized. A tall luggage or the like (for example, a foliage plant X) can be loaded.
Therefore, in the tonneau cover device 10 including the front tonneau cover 20 and the rear tonneau cover 30, the functionality of the tonneau cover device 10 can be further enhanced.

In this embodiment, the winding unit 31 of the rear tonneau cover 30 is configured to be removable from the slide rail 41.
Thereby, the front tonneau cover 20 and the rear tonneau cover 30 can be put into the retracted state by removing the rear end of the front tonneau cover 20 and the front end of the rear tonneau cover 30 from the slide rail 41 (see FIG. 13).
For this reason, all the sheet members covering the upper side of the cargo compartment T can be eliminated, and the cargo compartment T can be widened.
