DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt window opening and closing device for a vehicle, which opens and closes a window opening by tilting a window body with respect to a window opening provided in a vehicle body.

[0002]

2. Description of the Related Art Conventionally, as a rear window (rear quarter window) of a vehicle, a tilt window which opens and closes a window opening by tilting a window body with respect to a window opening provided in a vehicle body has been adopted. Various opening / closing devices for tilt windows are provided.

[0003] For example, FIG.
No. 678 discloses a vehicle tilt window opening / closing device 1 that includes a window body 5 made of a glass plate whose left end is rotatably connected to a window frame 3 of a vehicle body via a hinge (not shown).
The tilt movement is performed with respect to the window opening 6.

The vehicle tilt window opening / closing device 1 includes a drive mechanism 8 having a motor, a reduction gear mechanism, and the like (not shown) in a housing 7, and a first link 11 having a base end fixed to an output shaft 9 of the drive mechanism 8. And the base end is first
The second link 13 is rotatably connected to the distal end of the link 11, while being connected to the window body 5 via the hinge 12 at the distal end.
And

When the first and second links 11 and 13 are in the folded position shown by a two-dot chain line in the figure, the window body 5 closes the window opening 6 and the drive mechanism 8 moves the first link 11 in FIG. When the window body 5 is rotated to the unfolded position shown by the solid line, the window body 5 tilts and the window opening 6 is opened.

Since the vehicle tilt window opening / closing device 1 is provided on the vehicle body as a rear window (rear quarter window) of the vehicle as described above, the open / close state of the vehicle tilt window opening / closing device 1 is confirmed from the vehicle front side (for example, the driver's seat side). difficult. The tilt window opening / closing device 1 has a disadvantage that the opening / closing amount of the window body 5 is smaller than that of a normal power window (sliding opening / closing window body), so that it is more difficult to confirm the opening / closing state. Is easy to forget to close.
