PURPOSE:To provide an air supply device for supplying air with limited pressure and also provided with the function of making supplied air pressure variable. CONSTITUTION:In a main body housing 11, a flexible air tube 13 is installed on a pump unit 12 and a leak valve 15 and a pressure sensor 17 are connected branchingly. The leak valve 15 has a pressure adjust knob 16 for adjusting air pressure and pressure display means 16 is provided on the pressure sensor 17. A base frame 19 in a one-side opened square section shape is installed in the downstream side of this pressure sensor 17 so as to insert through the air tube 13 and a push-pressing means 20 for intercepting an air passage is arranged by the push-pressing deformation of the air tube 13 from upward by rendering this base frame 19 to a support stand. Thereby, the air pressure is set easily and even if an user is changed, quick responses can be carried out and the way to use is improved extremely. |
