Abstract: PURPOSE: To reduce energy loss by forming a rigid, integrally columnar body which consists of strips, each of which has a distal end and a proximal end, and has a fin. CONSTITUTION: The elongated strips are mounted at each other by their proximal ends 33 and distal ends 34. Connecting parts for mounting a suitable connector 34 for connecting a transducer to another device to be driven are mounted at the distal end of the column. As a result, the working electric power required by a handpiece is lessened if the transducer is included.

Abstract: PURPOSE: To achieve simplification of handling a tubular body by equipping the interior side of the tunnel with at least one of the resonance member inside the tunnel and with a fin extending radially in relation to the axis, and forming a longitudinal length hole which forms a concentric tunnel along the axis. CONSTITUTION: A tubular body 1 equipped with a fin extending radially has a longitudinal length hole which forms a central tunnel 8 having a concentric cross section with the axis of the tubular body. The tubular body forming a transducer contains 36 pieces of strip having a V-shaped cross section about 6.7cm long and the diameter of the tunnel 8 is determined to be large enough to accommodate the connection unit. Further, each strip which forms the fin is soldered or welded to a face ring 6 at its close and to a face ring 7 at its remote end, respectively. The transducer is equipped with the central tunnel 8 which accommodates connecting member 2 crossing the screw at the close end where the connecting part is connected to the transducer by putting the close end of the screw in the female screw of the face ring 6.
