Abstract: A tire air pressure abnormality warning device includes a transmitter for transmitting a signal of the air pressure of a tire measured by a pressure sensor, a portable device for opening and closing a door lock of a vehicle, and a vehicle-installed device for determining whether or not the signal from the transmitter indicates an abnormal air pressure of the tire and for driving the door lock by a signal from the portable device. The vehicle-installed device has a recording section for recording tire air pressure abnormality data. When the vehicle-installed device communicates with the portable device, it searches for any abnormality data from the recording section. If there is any abnormality data, it transmits a tire air pressure abnormality signal to the portable device. The portable device indicates a warning of abnormal air pressure of the tire by the tire air pressure abnormality signal using a warning indicating section.

Abstract: A switching device includes a switch body, a side knob, a returning mechanism, and a stopper. The switch body has a controlling unit which can be tilted and depressed. The switch body is surface-mounted on the printed circuit board. The side knob is attached to the controlling unit of the switch body. The switch body includes the returning mechanism for the controlling unit. The stopper is actuated in accordance with the tilting or depression of the side knob. The stopper is surface-mounted on the printed circuit board.

Abstract: A passive keyless entry system for unlocking and locking a door-locking mechanism by the operations of pulling and pushing the outside handle of a vehicle is provided. The passive keyless entry system for locking and unlocking the vehicle door comprises trigger switches. The switches are attached to the outside handle 1 for opening or closing the vehicle door. The trigger switches consist of a first switch 5 turned on or off in the position A where the operation of pulling the outside handle 1 from the normal position O is performed and a second switch 7 turned on or off in the position B where the operation of pushing the outside handle 1 from the normal position O is performed. The vehicle door is unlocked by the first switch 5 and is locked by the second switch 7.
