Abstract

An intermittent air blow gun () has a switching valve () including a switching-valve case () and a valve assembly (), and the valve assembly () includes: a valve body () configured to open and close a valve hole; a small-diameter piston () partitioning so as to form a small-diameter pilot chamber (); and a large-diameter piston () partitioning so as to form a large-diameter pilot chamber (). The valve body () is switched to a closed position when air discharged from an inside of the switching-valve case () to an air discharge section () is supplied to the large-diameter pilot chamber () through a bypass flow path (), and the valve body () is switched to an open position when air is exhausted.
