Claims

[Scope of Claim for Utility Model Registration] (1) In a key removal prevention device that activates an alarm when the driver's door is opened with the key inserted in the ignition key cylinder,
The alarm means is a device for preventing forgetting to remove a key, which is comprised of a sounding section that emits a warning sound and a light emitting section that illuminates a part or the whole of the periphery of the ignition key cylinder. (2) means for detecting whether or not a key is inserted into the ignition key cylinder; means for detecting opening/closing of the driver's door; and means for detecting whether or not an occupant is seated in the driver's seat; an alarm means comprising a sounding part that emits a warning sound to notify that the key has been forgotten, and a light emitting part that illuminates a part or the whole of the periphery of the ignition key cylinder, when the key is inserted into the ignition key cylinder. A device for preventing forgetting to remove a key, wherein the alarm means is activated when a driver's door is opened and no occupant is seated in the driver's seat.
