Abstract
An ultrasonic probe including a rotary transmission shaft to be rotated by a driver connected thereto, in which an oscillator is arranged in opposition to one end of the transmission shaft for emitting a ultrasonic wave, and a scanner such as a mirror is mounted to the one end of the rotary transmission shaft for reflecting the ultrasonic wave emitted by the oscillator to carry out an ultrasonic wave scanning. The rotary transmission shaft includes a first shaft having a first diameter, connected to the scanner, and a second shaft having a second diameter, connected to the driver with the first diameter being smaller than the second diameter. The oscillator as the scanner may be directly mounted to the end of the transmission shaft.
