PROBLEM TO BE SOLVED: To provide a tire pressure decrease warning adaptor which prevents the occurrence of tire accident, and can be found perceivably by the inspection of a driver, when the tire inflation pressure is reduced to appropriate abnormal values. SOLUTION: A cap member is put on elastic bellows member which introduce air in a tire, a press spring is attached elastically at the outside of a cap member, and a mirror surface object is attached to the bottom of a cap member. A vertical hole is arranged in the mirror surface object, in such a way that a colored warning indication part is inserted from the head of the warning adaptor body and installed perpendicularly, in a freely rising and setting way through the vertical hole. Moreover, the warning indication part is provided on the upper surface of the adapter body inner wall so that when the tire inflation pressure is reduced, the warning indication part is exposed, since the mirror-surface object sinks with accompanying the contraction of the bellows member, and the driver recognizes visually the warning indication part reflected on the mirror-surface object.
