An air valve device is adapted to be fitted into an opening of an inflatable article, and includes a valve seat having a seat body that is disposed between an inflating port and a conduit, and a valve disc unit disposed in the conduit to be moved between opened and closed positions, and having a valve disc connected with a plunger, an elastomeric seal ring superimposed on a padded region of the valve disc. A rigid retaining cap is disposed to bring a base layer of the seal ring in an abutting engagement with the padded region of the valve disc so as to secure the seal ring to the valve disc while permitting a sealing marginal layer of the seal ring to be air-tightly engaged with the seat body in the closed position. |
