Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an opening/closing device for a vehicle ceiling window device in which a cover member for opening and closing a window opening can be moved back and forth and tilted.

(Prior Art) This type of device makes the front part of the cover member freely movable back and forth and is pivoted, tilts the cover member from the window opening closing position to raise the rear part thereof, and then It is configured to be moved backward in a posture to open the window opening.

(Problem to be solved by the invention) The support part of the conventional cover member is only at the front part, and the rear part is not locked when the window opening is closed, so the rear part may be damaged by wind pressure etc. There was some levitation and vibration.

In view of these problems of the conventional device, the present invention provides a locking mechanism between the cover member and the driving body to lock the rear part of the cover member in a closed state, and also It is an object of the present invention to provide a ceiling window device for a vehicle in which this locking mechanism is activated in an operation other than the opening/closing operation to reliably prevent the cover member from floating up.

(Means for Solving the Problems) A feature of the present invention for achieving this object is that a cover member that can freely open and close an opening formed in the roof of a vehicle can move the driving body in the front and back direction. According to the opening/closing device for a ceiling window device of a vehicle, the rear portion of the opening/closing device is configured to move up and down, and the driving body may further move back and forth in a state where the opening is closed by the cover member. The cover member is provided so as to be able to move freely without moving up and down, and is removably engaged in conjunction with the play movement of the driving body to prevent the rear part of the cover member from moving upward. The mating portion and the engaged portion are provided on the rear lower surface side of the cover member and on the driving body side.

(Function) According to the present invention, from the state where the rear part of the cover member is raised and tilted up, by moving the driver forward, the rear part of the cover member lowers and closes the opening. If the drive body is further moved forward in this closed state, this forward movement is a play motion and does not affect the movement of the cover member. During this idle movement, the engaging portion and the engaged portion engage with each other, preventing upward movement of the rear portion of the cover member.
