<p>PURPOSE: To provide a small-sized electric motor vehicle in which the reduced state of air pressure of a tier wheel can be clearly notified to a driver. CONSTITUTION: In a small-sized electric motor vehicle having a body supported by tier wheels 2, 4 in such a manner as to be capable of traveling, it has a ground-to-body height detecting means 10 for detecting the height to ground of the body; and an alarming means for alarming a tire air pressure reduction when the height to ground of the body is less than a set value. Otherwise, it has a load detecting means for detecting the driving load of an electric motor 3 to the tier wheel driven by the electric motor 3; and an alarming means for alarming the tire air pressure reduction when the driving load of the electric motor 3 is a set value or more.</p> |
