装置。[Scope of Claim for Utility Model Registration] An ultrasonic transducer unit that can move forward and backward in the axial direction of the probe is provided inside the tip of the ultrasonic probe, and the ultrasonic transducer unit is moved at a constant speed via a shaft from a drive unit near the operator's hand. In an ultrasonic diagnostic device that moves forward and backward to obtain ultrasonic images at equidistant points for diagnosis, two pulleys are installed in the driving section, one of which is provided in a drive section so as to directly receive the driving force of a motor, and the other is a pulley that is hung between the two pulleys. An ultrasonic diagnosis characterized by having a passed belt and a holding member that rotatably supports a shaft and is fixed to the belt so as to be positioned between the center axes of the pulleys at a distance equal to the radius of the pulleys. Device.
