性を阻害するという問題があつた。 Conventionally, as shown in Fig. 2, a type of display using the movement of rubber bellows by air pressure is shown.
This is done by transmitting the movement of the rubber bellows to a cylindrical body installed above the bellows, and checking the positions of the colored red and blue display parts on the top and bottom of its outer surface through a see-through window in the casing. However, with this conventional display device, if, for example, the device is damaged while the vehicle is running or the rubber bellows is damaged, the air in the tire will suddenly flow out, and the installation of the device will actually reduce safety. There was a problem of inhibiting the
本考案はこれらの不都合な点を改善すべく種々

圧力の減少を防ぐようにしたものであ。 The present invention was developed through various studies in order to improve these disadvantages.The present invention utilizes the outflow pressure of air that occurs when the rubber bellows breaks to create a check valve that is integrated into the display device. This prevents the pressure inside the tire from decreasing.

固定したものである。 Hereinafter, one embodiment of the present invention will be explained based on the drawings.As shown in Fig. 1, an inverted cup-shaped frame body with a small through hole in the center and a valve seat in the lower part of this hole is used as a rubber bellows. An air valve opening pressing part is provided on the lower surface of the inverted cup-shaped frame, and the air valve opening pressing part has a groove in the center of the lower surface, the width of which is smaller than the diameter of a general-purpose valve core shaft head. Insert a ventilation plate with a deep hole to accommodate the rubber bellows, insert a ring-shaped gasket from below the ventilation plate, and connect the rubber bellows, the inverted cup-shaped frame, and the ventilation plate with a screw ring. is fixed to the casing.

トツパーである。 Also shown in the figure is an opaque plastic cup, which is insert molded into the casing. is a stopper that prevents the cylinder from falling downward.
尚、本考案の一実施例として装置の表示部が側
面にあるものについて説明したが、その形態はこ
れに限定するものでない。 Although an embodiment of the present invention has been described in which the display section of the device is located on the side, the configuration is not limited to this.
本考案は上述の如く構成されるので、例えば、
実車走行中に装置の破損やゴムベローズの破損が
生じた場合、タイヤ内の空気が貫通穴を通つて
急激に外部に洩れようとしても、その空気圧によ
つて球体が弁座に押し付けられタイヤの気密
を保つものであるから、きわめて安全で実用性の
高いものである。 Since the present invention is configured as described above, for example,
If the device is damaged or the rubber bellows is damaged while the vehicle is running, even if the air inside the tire suddenly tries to leak out through the through hole, the air pressure will push the ball against the valve seat and the tire will be damaged. Since it maintains airtightness, it is extremely safe and highly practical.
