(Effect of the Invention) According to the present invention, at the opening closed position of the panel 14, the rear part of the panel 14 is moved up and down by the first elevating means 35,
Since the rear part of the panel 14 is further moved up and down by the second elevating means 38 during the forward and backward movement of the panel 14 in the backward ascending posture, the amount of inclination of the panel 14 at the opening closed position is necessary for ventilation. If you open the opening 2 by moving the panel 14 backward,
Can be sufficiently rearwardly moved to provide an inclination amount that allows the opening area of the opening 2 to be large. As a result, the load when the panel 14 is moved from the closed posture of the opening 2 to the rearwardly inclined posture can be reduced, and when the panel 14 is traveling in the inclined posture at the opening closed position, the load from the front of the panel 14 is reduced. The wind pressure can be reduced, and the noise caused by the wind can be reduced. Further, when the panel 14 is changed from the inclined posture to the closed posture, the rear portion of the panel 14 is lowered from a position lower than the conventional position, so that the operating noise when closing the panel 14 can be reduced. Further, the lifter 15 is rotated around the front support portion by the first lifting means 35, and the moving body is lifted up and down by the second lifting means 38 to lift the lifter.
15 is rotated around the front support portion, that is, the first lifting means.
Since the panel 14 is inclined by combining the 35 and the second elevating means 38, the vertical width of the opening / closing device can be reduced, and the indoor space of the vehicle can be increased.
