Patent ID: 8192365

Claim:
An ultrasonic probe comprising; an ultrasonic transducer unit emitting ultrasonic waves while swinging, a motor, the motor adapted to generate power for swinging said ultrasonic transducer unit, a first power transmission device, the first power transmission device connected to a rotating shaft of said motor and transmitting said power, a drive device connected to said first power transmission device, the drive device rotated by said transmitted power, a cable-like second power transmission device, the cable-like second power transmission device adapted to transmit said power by the rotation of said drive device, wherein the second power transmission device includes a fixed end and an opposite end, a swing device, on which said ultrasonic transducer unit is mounted, swinging said ultrasonic transducer unit with said power due to the rotation of said drive device transmitted through said second power transmission device, a first fixing device to which the fixed end of the second power transmission device is fixed and which is removably, fixedly attached to said swing device together with said second power transmission device, and a second fixing device fixing, to said drive device, the opposite end of said second power transmission device, which is opposed to the fixed end that is fixed at the first fixing device, wherein an axis direction of the drive device and an axis direction of the rotation shaft of the ultrasonic transducer unit are configured to intersect.
