To provide a tire pressure alarm unit which has a simple configuration that helps reduce cost, can be used for trucks as a single tire pressure alarm unit, and is capable of wirelessly notifying a user when a low-tire-pressure alarm signal is generated thereby.SOLUTION: When air pressure inside a tire is lower than a predetermined set pressure value, pressure in an air chamber 25 of a base section 2 becomes greater than pressure in an upper accommodation space of the air chamber 25, which causes a central portion of a movable membrane 30 to move upward to deform the membrane into a concave shape, causing the movable membrane 30 to come into contact with a contact plate 4 to generate an alarm signal. An outer frame cover 40 is removably attached to the base section 2. A tire pressure alarm unit includes a near-field wireless communication module 10 that enables near-field wireless communication with an external communication terminal.SELECTED DRAWING: Figure 1

    【課題】簡単な構造でコスト低減を図り、トラック用として一種類のタイヤ空気圧警報器で対応できるとともに、警報装置がタイヤ空気圧不足の警報信号を発生した際に無線通信により利用者に通知する。【解決手段】タイヤ内の空気圧が所定の設定値より小さい場合、基底部2の空気室25内の圧力が空気室25の上方収納空間内の圧力より大きくなり移動膜30の中央部が上方に移動して凸状態になり、移動膜30と接触板4とが接触して警報信号を発生する。また、外枠カバー40が基底部2に着脱自在に取り付けられる。また、外部通信端末との間で近距離無線通信を可能にする近距離無線通信モジュール10を備える。【選択図】図1
