提供するものである。This invention was made to improve these conventional drawbacks, and it prevents twisting and kinking when fixing a soft protector, and also prevents twisting and twisting between the soft protector and the hard protector. The present invention provides an ultrasonic probe that removes air bubbles.
以下この考案の一実施例を図面により詳述する。An embodiment of this invention will be described in detail below with reference to the drawings.
第３図はこの考案の超音波探触子を示す図で、ａは超音

りリングおよび締付リングを示す斜視図である。Fig. 3 is a diagram showing the ultrasonic probe of this invention, where a is a cross-sectional view of the ultrasonic probe, and b and c are perspective views showing the sliding ring and tightening ring that are the features of this invention. .
同図において振動子１、硬質の保護体２、軟質の保護体
３、接触媒体４、リード線６、ダンパ７は第１図および
第２図に示したものと同様である。In the figure, a vibrator 1, a hard protector 2, a soft protector 3, a contact medium 4, a lead wire 6, and a damper 7 are the same as those shown in FIGS. 1 and 2.

両側面側に位置しかつ軟質の保護体３と接するようにな
っているすべりリングで、このすべりリングは例えば塩
化ビニール、ナイロン、テフロン等のプラスチックで形
成される。Reference numeral 10 denotes a sliding ring which is inserted into the inner cylinder 8a of the probe and is positioned on both sides of the ultrasonic transducer 1 and in contact with the soft protector 3. This sliding ring is made of, for example, vinyl chloride, Made of plastic such as nylon or Teflon.
