ABSTRACT:
A pen-like tire gauge includes a barrel body shaped as a pen, a guide cylinder secured in the barrel body, a plunger slidingly moving in the cylinder and carrying a semi-cylindrical scale having graduations marked thereon to dispose around the guide cylinder and resiliently tensioned by a restoring spring inserted in a bore of the barrel body, and an air adapter adapted to connect a tire inflating valve for measuring air pressure in the tire when the air is directed into the cylinder to force the plunger and to move the scale for its pressure reading and measurement through a transparent window formed on the body.
