PURPOSE:To provide an ultrasonographic bone evaluating device whose acoustic matching member is easy to be handled and is not necessary to be controlled, and which can scan freely an ultrasonic vibrator against an organism. CONSTITUTION:An freely deformable organism contact face 44 whose bottom frame 46 is a matching member storing part 42 is pressed on the organism surface. And the shape of the matching member storing part 42 seems to be bellows in its side wall 43 and has a vibrator attaching part with the ultrasonic vibrator 24 scanned by a scanning mechanism attached thereto and the organism contact face 44, and stores the acoustic matching member in its inside space. Therefore, when the ultrasonic vibrator 24 is scanned in an arbitrary direction by the scanning mechanism, the side wall 43 of the matching member storing part 42 deforms depending on the motion of the ultrasonic vibrator 24 accompanying the scanning, and absorbs the motion and makes the scanning smooth, always fills an ultrasonic transmission pathway with the acoustic matching member and maintains the tight adhesion of the organism contact face 44 against the organism surface. |
