Abstract
A hand air pump includes a cylinder having mutually communicated relatively large chamber and relatively small chamber, a mount sealingly mounted on the top of the cylinder and including an air passage communicated with the relatively small chamber, and a pressure gauge pivotally connected to the mount. The pressure gauge is pivotable between a storage a position and an operative position. In addition, the pressure gauge is communicated with the air passage at the storage position and at the operative position. A nozzle is communicated with the air passage for inflation.
