When the timing member 38 moves rearward at the end of this operation and the pin 42 reaches the rear end of the groove 43, the engagement port 41 faces the square hole 45, and the timing cam body 46 can be engaged with the engagement port 41. The subsequent movement of the slider 6F is transmitted to the interlocking body 8 via the timing member 38. When the interlocking body 8 attempts to move backward, the timing cam 46 is pushed out from the engagement notch 47, and The lock of the guide rail 5 is released (FIG. 11), and the timing cam body 46 is engaged with the engagement opening 41 so that the interlocking body 8 and the timing member 38 move integrally. When the lock of the interlock 8 is released and the slider 6 moves backward thereafter, the interlock 8
The bracket 4 and the panel 3 move together with the slider 6 and move the panel 3 rearward to the open position C where the opening 2 is almost fully opened. The movement of the panel 3 from the open position C to the closed position A is the reverse operation. Panel 3
Is in the closed position A, the front portion of the groove 40 is in a horizontal state, and when the slider 6 is moved forward, the timing pin 36 of the front slider 6F only moves in the groove 40, and 9F and the timing member 38 are not actuated, so the front of the panel 3 is stationary. The forward movement of the rear slider 6R moves the rear lifting / lowering body 9R forward.
(2) The rear part of the panel 3 is lifted through the rear elevating means 10R, 11R. The panel 3 performs a tilt-up operation centering on the first cam pins 49 and moves to the raising posture D (however, passes through the overrun state at the beginning of the tilt-up operation). When the slider 6 is moved backward from the state in which the panel 3 is in the raising position D and the panel 3 is tilted down, it passes through the lowering position B and descends to the overrun state, and then slightly tilts up. To the closed position A. As a result, panel 3 always rises and then closes position A
And the turning up of the weather strip 22 is prevented. It should be noted that the present invention is not limited to the above embodiment, but can be variously modified. For example, the structure in which the panel 3 is tilted from the closed position A to the raised position D has been described. However, the present invention can also be applied to a device in which the panel 3 is not tilted. In this case, the groove 40 is formed only with the downwardly inclined portion and the first cam groove. 15 deletes the elevating part P. Further, the front lifting mechanism 7F of the embodiment may be combined with the conventional rear lifting mechanism. According to the present invention described in detail above, the panel 3
