Claims

[Scope of utility model registration request]

Inside the tip of the tubular container, there is an ultrasonic vibrator, an iron core surrounded by permanent magnets and around which a coil is wound, and one end of a rotating shaft protruding from the iron core, which faces the ultrasonic vibrator. The other end of the rotating shaft is formed into a tapered shape, and a conductive member is provided that is insulated from the rotating shaft and is electrically connected to the coil. 1. An intrabody cavity ultrasonic scanning device characterized in that it is supported by an elastic member or an elastic member interposed with a conductive member.
