(C) When slide is opened When it is desired to obtain a wider opening from the above tilt-up opening state, the motor 25 is further driven. Then, since both link members 21 and 22 are in a united state, the driving force transmitted from the geared wire 240 to the guide link member 21 is a slide link via the hooking protrusion 215 and the hook 28 in the hooking state. It is also transmitted to the member 22 and both slide, and both link members 21 and 22 and the tilt link
The driving force is also transmitted to the lid 16 via the 23 and the auxiliary link 24, and the lid 16 is guided by the slide rail of the slide means S and slides rearward.

In the fully opened state of the lid 16, the frame opening can be opened widely to obtain a large opening area, and direct sunlight can be taken into the room or a feeling of opening can be obtained. The rear slide amount of the lid 16 depends on the link member guide portion 201 of the guide rail 20.
It is regulated by a stopper (not shown) provided at the rear end portion of the rear.

(D) When closing the lid 16 when the slide is closed, see (b) and (c) above.
The motor 25 is driven by the rotation in the opposite direction to the case. As a result, both link members 21 and 22 slide forward in the combined state, and along with that, the lid 16 also slides forward,
Return to the tilt-up opening state of (b).

In the initial stage of driving the motor 25, the guide link member 21 is slightly moved relative to the slide link member 22 by a gap t between the rear end of the hook hole 281 shown in FIG. Both the link members 21 and 22 slide forward as the hooking protrusion 215 slides forward and pushes the front end of the hook hole 281.

However, when the lid 16 is slid and opened, the stopper roller 27 contacts the roller guide portion 204,
Since the rotation of the hook 28 is regulated, the linked state of both link members 21 and 22 is maintained, and tilting down does not occur during sliding.

Then, when returning to the tilt-up opening state of FIG. 5 in this state, the stopper bracket 224 of the slide link member 22 abuts on the stopper fixed to the guide rail 20, and the movement of the guide link member 22 is restricted. To be done. At this time, the stopper roller 27 of the hook 28 is
5, the guide link member 21 slides further forward, and the guide rod 214 comes out, the hook 28 rotates based on the urging force of the spring 29, and the stopper roller 27 stops. It falls into the recess 205,
Both link members 21 and 22 are no longer united.

(E) Tilt down When the motor 25 is further rotated in the opposite direction from the above (d) or (b) state, both link members 21 and 22 are separated from each other, and the tilt link 23 and the auxiliary link 24 based on this are separated.
The front end portion of the lid 16 is lowered by the reverse rotation of, and the lid is closed as shown in (a).

Although the embodiment has been described with reference to the drawings, the specific configuration of the present invention is not limited to the above-described embodiment. For example, in the embodiment, the motor is used to perform tilt up / down and slide. It may be driven by a hydraulic device other than the motor, or may be manually opened and closed without providing a driving means.

Further, although the tilt up / down and the slide are performed by one driving means, the driving means may be separately provided.

Further, although the rail-shaped member is shown as the slide member, a rod-shaped member may be used.

[Effects of the Invention] As is apparent from the above description, according to the lid opening / closing device of the present invention, the opening can be opened by sliding or tilting up. It is possible to achieve both the feeling and the ventilation even during rainfall by tilting up, and at the same time, the rigidity during tilting up can be secured with a simple structure that does not increase the weight. .
