Abstract
An ultrasonic vibrator has a very versatile, simple structure without a rotational structure. In order to infallibly prevent drops of water from entering the inside of the casing of the vibrator even if autoclave sterilization is performed without a drying process, the ultrasonic vibrator has a connecting member and a partition member, each used as a barrier plate member making up the inside of the vibrator body. The ultrasonic vibrator additionally has O-rings disposed in a packing, an electrode, and an airtight cap. By the O-rings, water is prevented from entering a lumen of a transducer. The electrode is insulated by a sealing agent, and a short circuit is presented.
