Claims (1)

[Claims for Utility Model Registration] (1) A detector that comes into contact with the object to be inspected to detect the vibration of the object, and a detector that detects the vibration state of the object based on the detection signal from this detector. A vibration testing device comprising a main body of the testing device to be tested, a gripping portion mounted to be movable relative to the detector, and a gripping portion interposed between the gripping portion and the detector to detect relative pressure between the two. pressure sensing means for
A vibration testing device comprising: proper pressure display means that is connected to the pressure detection means and displays that the relative pressure substantially matches the rated contact pressure of the detector. (2) In paragraph 1 of the claims for utility model registration,
A vibration testing device characterized in that the appropriate pressure display means is a display lamp, and the pressure detection means is a pressure switch that is turned on and off in response to the relative pressure. (3) In paragraph 1 of the claims for utility model registration,
A vibration testing device characterized in that the pressure detection means is a pressure sensor that generates an output signal corresponding to the relative pressure. (4) In paragraph 3 of claims for utility model registration,
A vibration testing device characterized in that the appropriate pressure display means is a meter that displays an output signal from the pressure sensor. (5) Scope of claims for utility model registration, paragraph 3 or 4
2. The vibration testing device according to item 1, wherein the appropriate pressure display means is an indicator lamp connected via comparison means for comparing the output signal from the pressure sensor with a preset reference value. (6) Scope of claims for utility model registration, paragraphs 1 to 6
2. The vibration testing device according to claim 1, wherein a space between the detector and the gripping portion is filled with hydraulic oil, and the pressure detection means is capable of detecting the hydraulic pressure of the hydraulic oil.
