Abstract
A tire deflation alarm apparatus to be provided on a vehicle with air-filled tires, comprising: a timer for measuring a period of time from when the air pressure of a tire is set to a normal value to the time when the air pressure spontaneously drops to a dangerous value, the period of time being established beforehand; an alarm portion connected to the timer and designed to give an alarm after the period of time has elapsed; and a reset switch for resetting the timer to the zero hour. The apparatus is capable of warning the tire's spontaneous air pressure drop that inevitably occurs when allowed to stand.
