If the receiving member 27 fixed to each operation link 26 is displaced until it is located on the upper surface side of the arm 3 through the connecting portion of the arm link 21 and the arm 3 by rotating the arm link 21,
Since the receiving of the arms is released, each arm 3 slides the rolls 17, 20 of the guide plate 12 by its own weight and begins to retract. Since the outer end of each arm 3 is connected to the column 1 via the arm link 21, the arm 3 is connected to the 14th arm.
While retreating as shown in the figure, start turning counterclockwise with pin 25 as a fulcrum. At this time, the roof frame 6A corresponding to the arm 3 is also retracted substantially along the arm 3 while being guided by the roll 31 of the L-shaped link 29.

Since the movable tube 45 is pulled up by the wire rope 66 as the arm 3 moves backward, the roof frame 6 is folded toward the vertical axis 41 via the panto column 61. Above arm 3
As shown in FIG. 15, when the vehicle retreats to the storage position along the column, the movable cylinder 45 is also displaced to the lowest position, so that the roof bone 6 is completely folded together with the seat 7.

In this case, since the parasol portion 5 is folded and brought close to the column 1 in conjunction with the arm 3 retracting to the storage position along the column, the space on the side of the column 1 can be used without waste. .

In the above embodiment, the parasols 5A and 5B corresponding to the two columns 3A and 3B are opened and closed.
Even if the number of columns 3 is increased to open and close three or more parasols 5 at the same time, the same effect can be obtained.

[Effects of the Invention] As described above, according to the present invention, the parasol portion is supported on each inner end portion of the plurality of arms laterally extended at the respective upper ends of the plurality of columns, so that the storage operation of the arm is performed. Since the parasol part is interlocked to draw the parasol part around the pillar while pulling it toward the pillar side, it is possible to effectively use the space around the pillar in the folded state.

Particularly, since the parasol portion can be integrally opened and closed through each arm by connecting the arm links and the like that are connected to the above-mentioned arm, it is possible to promptly meet the demand for a large roof area.
