To automatically maintain an air pressure of a tire inner space at a prescribed pressure with a simple structure.SOLUTION: A tire air pressure adjusting device comprises: a high pressure tank in which an inner space is formed as a high pressure space where high pressure air is held by an air pressure in the tire inner space, and in which the high pressure space is communicated with the tire inner space through a communication passage; and a pressure adjusting mechanism having a piston operated according to the air pressure of the tire inner space, a pressure adjusting valve which opens and closes the communication passage according to the operation of the piston and a pressure adjusting spring energizes the piston in a direction in which the pressure adjusting valve is opened. In a state where the air pressure of the tire inner space is lower than a prescribed pressure, the communication passage is released by operating the piston.SELECTED DRAWING: Figure 3
【課題】簡素な構成で自動的にタイヤ内空間の空気圧を所定の圧力に保つ。【解決手段】内部空間が前記タイヤ内空間の空気圧より高圧の空気が保持される高圧空間として形成されると共に前記高圧空間が前記タイヤ内空間と連通路によって連通された高圧タンクと、前記タイヤ内空間の空気圧に応じて動作されるピストンと前記ピストンの動作に伴って前記連通路を開閉する調圧弁と前記ピストンを前記調圧弁が開弁する方向に付勢する調圧バネとを有する調圧機構とを備え、前記タイヤ内空間の空気圧が所定の圧力より低下した状態において前記ピストンが動作されることにより前記連通路が開放される。【選択図】図3
