On the other hand, the drive unit 3 includes a drive motor 6a (rotational power unit 6) and a geared wire 7 for expanding and contracting the extendable unit 2.
And a transmission gear mechanism 8 disposed between the geared wire 7 and the drive motor 6a. The geared wire 7 has a gear formed along the longitudinal direction of the wire member. The distal end is fixed to the distal end of the telescopic rod 5, that is, the inner surface of the window pushing portion 23, and the other end is inside the housing 21. By being introduced, it is accommodated in a spiral shape along the inner peripheral surface of the housing 21. The drive motor 6a is disposed so that the rotating shaft 6s is located at the center of the housing 21.
A transmission gear mechanism 8 is disposed between the rotating shaft 6s and the geared wire 7. The transmission gear mechanism 8 includes a pinion 25 provided on the rotary shaft 6s, and an intermediate gear 26 disposed between the pinion 25 and the geared wire 7. The intermediate gear 26 can set the expansion and contraction speed of the expansion and contraction section 2 by combining a plurality of gears.

The control unit 4 is configured as shown in FIG. Reference numeral 31 denotes a control unit main body, which has a microcomputer function. The output section of the control section body 31 has a drive motor 6

There is no adverse effect of leaving scars and dirt on the mounting.

Next, an automatic window closing device 1 according to a modified embodiment will be described with reference to FIGS.

In the above embodiment (basic embodiment), the drive motor 6a is exemplified as the rotary power unit 6, but a spring 6b may be used instead of the drive motor 6a. In this case, if the timer unit 10 is configured as a mechanical type using a mainspring or the like, the power supply unit 34 becomes unnecessary. Therefore, the timer unit 10
, The operation start time is set and the mainspring 6b can be used by winding the mainspring 6b. Thus, when the operation start time is reached, the pinion 25 is rotated by the mainspring 6b. The method of use is the same as in the basic embodiment described with reference to FIGS. In such a modified embodiment, there is an advantage that the power supply section can be made unnecessary, which is economical, and can be implemented at low cost because the configuration is simplified.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment.
For example, the closed window can be automatically opened by hooking the stopper portion and the window pushing portion on the window frame and the window, respectively, and shortening the stretchable portion from the extended state. Further, the sensor unit is not limited to the example, and any other sensor that detects an environmental state can be used. Others
The configuration, shape, material, quantity, and the like of the details can be arbitrarily changed without departing from the gist of the present invention.
