検出装置。 A transmission unit is created by integrating a power supply device, an oscillation circuit that performs oscillation operation in response to a detection signal from a pressure sensor installed to detect tire air pressure, and a vibrator excited by the output of this oscillation circuit. and an attachment that is selected depending on the shape of the tire hub and connects the tire hub and the transmission unit, and transmits the natural vibration due to the excitation output of the vibrator to the vehicle body side through the attachment and the tire hub. 1. A tire air pressure detection device for a vehicle, characterized in that the device is configured to transmit air pressure and includes a vibration detection device on the vehicle main body side that detects natural vibration caused by the excitation output of the vibrator.
