PROBLEM TO BE SOLVED: To enable battery exchange by enabling assembly and disassembly by applying improvement to a conventional tire air pressure alarm and installing a cover to be detachably mounted.SOLUTION: Disclosed is a tire air pressure alarm 1 which is attached to a cap of a tire valve, in which, when air pressure in a tire becomes a proper value or less, a current flows and a conducted circuit is formed, and in which an alarm device generates alarm signals showing shortage in tire air pressure. In order to improve airtightness, an outer frame cover 100 is provided which covers the outer peripheral surface of a bottom seat 2, a consecutive cover 4 and an alarm device 10 and the outer frame cover 100 is detachably mounted, thereby enabling assembly and disassembly.SELECTED DRAWING: Figure 1 |
