PURPOSE: A tube type ultrasonic vibrating device is provided to improve cleaning efficiency by installing a vibrating block having a plurality of vibrating members at a vibrating tube and uniformly transferring ultrasonic vibration. CONSTITUTION: A tube type ultrasonic vibrating device is composed of a semicylindrical vibrating block(12), a plurality of vibrating members(13) fixed to the top of the vibrating block, piezoelectric elements(17) installed at the bottom of each vibrating member, a cylindrical vibrating tube(11) covering the vibrating block, cover plates(11a) installed at both sides of the vibrating tube, and a power cord(15). The power cord is connected to a wire(14) grounded on the piezoelectric elements.
