A pulsating vibration air generation apparatus capable of sharply and quickly controlling air flow in turning on and off operation, thereby generating a pulsating vibration air with sharp and hardly attenuated peak and valley, and capable of operation without occurrence of so much mechanical vibration. The pulsating vibration air generation apparatus is comprised of a main body having a tubular hollow space R2 with which two air communication ports are associated, and a rotary body situated for rotation in the tubular hollow space R2 and which has a peripheral side surface S4c so as to slide on the inner surface S2c forming the tubular hollow space R2.
