A through hole 11a is formed in the upper wall of the frame 11 for inserting a locking rod 18 which will be described later, and a lower protruding portion 11b is formed on the lower surface side of the upper wall of the frame 11 in the through hole 11a forming portion. There is. On the side wall of the frame 11, a plate-shaped supporting member 13 having laterally arranged portions 13a and 13b is attached by rivets 14 and 14. A leaf spring 15 is attached to the upper horizontal portion 13a of the support member 13 with a rivet 16, and an exciting coil 20 having a contact portion 20a at its upper end is erected on the lower horizontal portion 13b. ing. The exciting coil 20 is connected to terminals 21 and 21 protruding from the frame 11. The leaf spring 15, the support member 13 and the exciting coil 20 constitute a driving means.

A contact member 17 is provided near the center of the leaf spring 15, and a locking rod 18 is attached to the tip of the leaf spring 15 in the vertical direction of the leaf spring 15 by welding. The upper end of the leaf spring 15 is in contact with the lower protrusion 11b of the frame 11. The lower portion of the locking rod 18 passes through the through hole 7a of the IG key cylinder outer 7 as the leaf spring 15 is deformed downward.
The IG key cylinder inner 6 is fitted into the locking recess 9 and has a tip end having an inclination corresponding to the non-locking portion 9a of the locking recess 9. On the other hand, the upper portion of the locking rod 18 is inserted into the through hole 11a of the frame 11 and protrudes from the column cover 2a of the steering column 2. An operating portion 19 is provided at the upper end of the locking rod 18 protruding from the column cover 2a. The locking rod 18, the operating portion 19 and the locking recess 9 of the IG key cylinder inner 6 constitute a locking means.

On the other hand, inside the door of the automobile, as shown in FIG. 3, a window open / close detection switch 23 for detecting the open / closed state of the window glass 22 is provided. Wind glass 22
Can be opened and closed by a drive motor (not shown) provided in the door and an operation switch in the vehicle for operating the rotation of the drive motor. A receiving member 25 is fixed to the lower end portion of the window glass 22 via an interposing member 24. The lower surface of the receiving member 25 is provided with a pressing plate 27 that turns the window opening / closing detection switch 23 on and off by pressing and releasing the window opening / closing detection switch 23 against the moving rod 26. The window opening / closing detection switch 23 and the pressing plate 27 constitute window opening / closing detection means. Above window open / close detection switch
23 is attached to the door panel 28 with screws 29,
As shown in FIG. 4, the outside is covered with a frame 30. Terminals 31 and 32 are provided on the frame 30 in a protruding manner, and a conductive leaf spring 33 whose urging direction is downward is attached to the upper terminal 31 with a rivet 34. A movable contact 35 is provided at the tip of the leaf spring 33, and the movable rod 26 is suspended in the center with its upper end fixed. Also,
A contact support member 36 is attached to the frame 30 with a rivet 37, and a leaf spring 33 is mounted on the contact support member 36.
A fixed contact 38 that abuts the movable contact 35 of is provided.
The fixed contact 38 is connected to the lower terminal 32 provided on the frame 30. A lower lid 39 is provided at the lower end of the frame 30.

Further, the terminal 31 of the window open / close detection switch 23
As shown in FIG. 5, one of the 32 is connected to the battery 40 via the ignition switch 4, and the other is
It is connected to one terminal 21 of the exciting coil 20. The other terminal 21 of the exciting coil 20 is grounded.

In the above configuration, when the engine is rotating, the IG key cylinder inner 6 of the ignition switch 4 is rotated to the ON position shown in FIG. 1, and the window glass 22 can be opened / closed by the operation switch in the vehicle. Has become. Here, when the window glass 22 is opened, the pressing plate 27 moves downward, whereby the pressing of the window opening / closing detection switch 23 on the moving rod 26 is released,
Due to the urging force of the leaf spring 33, the movable rod 26 moves downward and the movable contact 35 comes into contact with the fixed contact 38. As a result, the window open / close detection switch 23 is turned on, and the exciting coil 20 is supplied with power from the battery 40.
Is excited and the leaf spring 15 is pulled down. With this operation, the locking rod 18 moves downward, and the tip end of the locking rod 18 is fitted into the locking recess 9 of the IG key cylinder inner 6. Therefore, in this state, that is, in the opened state of the window glass 22, the IG key cylinder inner 6 is locked in the counterclockwise direction.
It will not be possible to rotate to position and the engine cannot be stopped. However, since the non-locking portion 9a is formed in the locking concave portion 9, the IG key cylinder inner 6
Can be rotated in the clockwise direction, and the engine can be started in the above state.

On the other hand, when the window glass 22 is closed, the moving rod 26 of the window open / close detection switch 23 is pressed by the pressing plate 27 to move the leaf spring.
Moved upward against the bias of 33. As a result, the leaf spring 33 is moved upward, the fixed contact 38 and the movable contact 35 are separated from each other, and the window opening / closing detection switch 23 is turned off.
The energization of the exciting coil 20 is cut off. Therefore, the leaf spring 15
Move upward, and at the same time, the locking rod 18 moves upward,
The lock of the key cylinder inner 6 is released. For this reason, the IG key cylinder inner 6 becomes rotatable, and the ignition switch 4 can be turned off.

Further, if the user wants to consciously stop the engine with the window glass 22 opened, pulling up the operating portion 19 provided at the upper end of the locking rod 18 causes the IG
The key cylinder inner 6 is rotatable and the engine can be stopped.

The location of the window opening / closing detection switch 23 is not limited to the above-mentioned location, and may be any location as long as the opening / closing of the window glass 22 can be detected. Also,
The window opening / closing detection switch 23 is provided with a relay, and conversely, when the window opening / closing detection switch 23 is in the OFF state, the exciting coil 20
It is also possible to excite. Further, as a means for fitting the locking rod 18 into the locking recess 9 of the IG key cylinder inner 6, a diaphragm (vacuum), a motor or the like is used in addition to the means utilizing the magnetic force of the exciting coil 20 as described above. It may be one.

〔The invention's effect〕

As described above, the structure for preventing forgetting to close the window of the vehicle according to the present invention includes the locking means for preventing the ignition switch from rotating in the engine stop direction by engaging the ignition switch, and the opening / closing of the windshield of the power window. The window open / closed detecting means for detecting the state, and when the window open / closed detecting means detects the open state of the window glass, the locking means is driven in the locking direction, while the closed state of the window glass is detected. When the windshield is open, it is possible to prevent the engine from being stopped by the ignition switch, since the drive means is provided to drive the locking means in the unlocking direction when the windshield is opened. . Therefore, it is possible to prevent the forgetting to close the windshield.
