LED EMISSION TYPE PNEUMATIC PRESSURE CHECKER OF TIRE

摘要

[PROBLEMS] To provide an LED emission type pneumatic pressure checker of a tire by which the pneumatic pressure check of a vehicle tire can be performed easily regardless of whether it is a light place or a dark place by lighting or flickering an indication lamp such as an LED thereby indicating the color. [MEANS FOR SOLVING PROBLEMS] An operating member (5) in a check means (2) is operated toward the direction of the fixing shaft of a valve core (b) which is thereby opened. Air in a tire is then introduced into the body section (1) and a detection body (6) moving amount of which is varied in the direction of the fixing shaft of the valve core depending on the level of pressure of the introduced air is detected by detection means (7, 8). According to a detection signal from the detection means dependent on the variation in moving amount of the detection body, a lamp (9) indicating a proper pneumatic pressure of the tire or a lamp (10) indicating an improper pneumatic pressure of the tire is lighted or flickered for displaying to the outside of the body section.
