The center roll bar 21 is a gate-shaped pillar that is integrally formed with the vehicle body 11, and stands up on both left and right sides at the rear of the driver's seat. On the other hand, the quarter pillar 22 is formed in a gate shape similar to the center roll bar 21, and as shown in FIGS. Both legs of the screw 23 are attached via nuts 24 onto each long screw 23 extending in the direction. The screw 23 and the nut 24 constitute a ball screw type feeding mechanism,
By rotating both screws 23 in the forward and reverse directions using a drive means (not shown), the quarter pillar 22 can be moved to any position in the front-rear direction along each screw 23 and fixed at the moved position.

Both slide shutters 30a and 30b have the same configuration, and as shown in FIG.
1... are connected, and a chain 32 is attached to both front and rear ends thereof. Of each slat 31, the one on the tip side corresponding to the roof is an aluminum plate, and the remaining slats are synthetic resin plates. Each of these slats 31 has a fifth
As shown in the figure and FIGS. 6a and 6b, a pair of fitting recesses 31a extending in the longitudinal direction on both sides thereof,
31b is formed. These fitting recesses 31
A and 31b have a circular cross section, and extend from the circular portion to the side edge and have a slit-like opening.

On the other hand, the connecting members 33 that connect the slats 31 to each other are flexible and made of synthetic resin.
It is formed to have approximately the same length as each slat 31.
Each connecting member 33 has a pair of rod portions 33a, 33b.
, a plate-shaped first connecting part 33c that connects these two, a plate-shaped second connecting part 33d extending perpendicularly from this intermediate part, and an umbrella-shaped seal part 33e extending perpendicularly from this intermediate part. It is made up of. In such a connecting member 33, both slats 31 are connected to each other by fitting each rod portion 33a, 33b into each fitting recess 31a, 31b of both adjacent slats 31, and in this state, the second slat 31 is connected to each other. A connecting portion 33d extends from between both slats 31 toward the front side, and both ends of the sealing portion 33e are elastically in close contact with the front side edges of both slats 31. As a result, the connecting member 33 sufficiently allows relative rotation between the slats 31 and seals the slats 31 liquid-tightly from their surfaces.

Center roll bar 21 and quarter pillar 2
2, as shown in FIGS. 7 and 8, the inner edges facing each other are formed into a substantially U-shaped cross section, and holders 25a and 25b having a U-shaped cross section are installed in these recesses. Through the guide rail 26a,
26b is attached. A guide roller 34 provided on the outside of the chain 32 of each slide shutter 30a, 30b is connected to each guide rail 26a, 26b.
The slide shutters 30a, 30b are fitted into the respective guide rails 26a, 26 so as to be able to roll.
Slide along b. Each holder 25a, 25
Seal members 27a and 27b are fixed to the outer ends of b, and their lip portions are in close contact with the surfaces of both ends of the slat 31.

The winding drums 41, 41 have the same structure, and the terminal ends of the slide shutters 30a, 30b are fixed, and the built-in torsion springs always act to keep the slide shutters 30a, 30b fixed.
It is biased in the direction of winding up 30b. Further, each of the transport mechanisms 42, 42 has the same configuration, and each slide shutter 30a, 30b is carried in and out of each winding drum 41, 41 by driving an electric motor that rotates forward and backward.

In the opening/closing mechanism configured in this manner, the transport mechanisms 42, 42 can be driven in the forward and reverse rotation directions and stopped by a switch provided in the vehicle interior, and thereby the slide shutters 30a, 30
b can be opened and closed. That is, when the transport mechanisms 42, 42 are driven in the state where the slide shutters 30a, 30b are closed as shown in FIGS. 1 and 9a, the transport mechanisms 42, 4
2 sequentially winds up the slide shutters 30a and 30b according to the amount of conveyance. Therefore, the slide shutters 30a and 30b slide from above to the sides to below along the center roll bar 21 and the quarter pillar 22, and when their tips descend to predetermined positions, the transport mechanisms 42 and 42 The drive stops. In this state, as shown in Figure 9b,
Both sides and the upper part of the rear part of the vehicle body except the quarter pillar 22 are all opened.

Further, in order to close the rear part of the vehicle body which is in the open state, the conveying mechanisms 42, 42 are driven in the opposite direction to move the slide shutters 30a, 30b to the winding drum 41,
41. As a result, the slide shutters 30a and 30b gradually slide upward and inward along the center roll bar 21 and the quarter pillar 22, and when their tips reach the upper center, they fit into each other in a fluid-tight manner. At the same time, the transport mechanisms 42, 4
2 stops. In this state, the entire rear part of the vehicle body is closed, as shown in FIGS. 1 and 9a.

Note that in this embodiment, quarter pillar 2
2 is assembled via a nut 24 onto the left and right screws 23 constituting the ball screw type feed mechanism.
The quarter pillar 22, which is movable in the longitudinal direction and is located at the position shown in Fig. 9b, is moved to the back of the center roll bar 21 as shown in Fig. 9c after lowering the rear window glass, and the rear of the vehicle body is moved. It can be opened completely.

By the way, in this embodiment, since the respective slats 31 constituting the slide shutters 30a and 30b are connected by the connecting member 33, the connecting member 3
Adjacent slats 31 are connected at a predetermined interval by both rod portions 33a, 33b constituting the slats 3 and a flexible first connecting portion 33c.
This allows for smooth and sufficient relative rotation between the two. Therefore, the slide shutters 30a, 30b smoothly slide along the center roll bar 21 and quarter pillar 22, even though they are largely curved.

Furthermore, on the front surface side of each slat 31, the flexible seal portion 33e constituting the connecting member 33 spans both slats 31 and is always in elastic contact with the slat 31. To reliably seal the connecting portion of each slat 31 without hindering the relative rotation of the slats 31.

The slide shutter according to the present invention can be used not only as an opening/closing mechanism at the rear of a vehicle body, but also in various opening/closing mechanisms that require a slide shutter.
