Abstract

PURPOSE:To suppress the generation probability of a continuous air feed state to an extremely low level, by connecting an air/water feed selection switch and a proper number of ON/OFF operating switches to an electric circuit, wherein an air feed control valve and a water feed control valve are connected in parallel, in series. CONSTITUTION:In such a state that a push button 47 is not pushed and both of an air/water feed selection switch 23 and an ON/OFF operating switch 25 are opened, air and water are not fed. When the push button 47 is brought to a half-pushed state, both of the air/water feed selection switch 23 and the ON/OFF operating switch 25 becomes a closed state. Therefore, an air feed control valve 15 is opened to feed air. When the push button 47 is perfectly pushed, the air/water feed selection switch 23 is opened and the ON/OFF operating switch 254 becomes a closed state. Therefore, a water feed control valve 17 is opened to feed water. As a result, probability bringing about continuous air feed state becomes an extremely low level. When the hand of an operator is separated from the push button 47, the push button 47 rises by the energizing force of a spring 49 to be returned.
