Abstract
A valve apparatus for an air tool which has a valve rotatably disposed in a cylinder portion of a body of the air tool in which an air motor is accommodated; and a lever fixed to the valve and slidably received within a slit-shaped opening formed in the cylinder portion. The valve includes a first disc portion having an air inlet, a lever-fixing portion having an air passage which communicates with the air inlet, and a second disc portion having an air outlet which communicates with the air passage. The lever-fixing portion is narrower than the first and second disc portions. The lever has a knob portion slidable within the opening and a generally U-shaped engagement portion fixed to the lever-fixing portion so that two legs of the engagement portion sandwich the lever-fixing portion from diametrically opposite sides.
