During normal and reverse swings of a transducer main body, an engagement accuracy is ensured to reduce generation of vibration and noise. An ultrasonic transducer includes: a coupling swingably and loosely fitted between one end portion of an output shaft of a power source that swings the transducer main body and the transducer main body, and a flywheel swingably and loosely fitted to another end portion of an output shaft of the power source, ensuring the reduced vibration and noise from the transducer main body.

Ultrasonic transducer

A probe for ultrasonic diagnostic equipment includes a cable, a cable outer periphery holder, and a depressed cone shape component. The cable outer periphery holder includes a deformable convex cone shape portion and a supporting surface that holds an outer peripheral of the cable. The depressed cone shape component has a depressed cone shape portion and fits the convex cone shape portion. The cable outer periphery holder has a water proof structure configured to prevent invasion of liquid from a gap formed between the outer periphery of the cable and the supporting surface. The water proof structure is configured to have the convex cone shape portion and the depressed cone shape component to fit so as to deform the convex cone shape portion. The deformation forms a reduced diameter portion to eliminate the gap, the reduced diameter portion having a diameter.
