Abstract: A pressure checker for a pneumatic tire having a tire valve, including a cap member defining an open ended chamber therein and adapted for sealing threaded engagement with the tire valve, a pressing member provided in the chamber and adapted to press the tire valve open when the cap member is threaded on the tire valve, and inflatable membrane provided in the chamber and inflatable by an air pressure released from the tire when the tire valve is opened by the pressing member so that from the degree of deformation or inflation of the membrane an observer can check the air pressure of the tire.

Abstract: A windshield washer having a jet nozzle adapted for ejecting a washing liquid to a windshield, a first reservoir for containing a first liquid such as water, a second reservoir for containing a second liquid such as a detergent solution, and a pump having a rotor for feeding the first or second liquid to the jet nozzle. By rotating the rotor selectively in the forward or reverse direction, the desired first or the second liquid is ejected from the jet nozzle as the washing liquid.
