Claims

[Scope of Claim for Utility Model Registration] (1) A vibrating string, a plate-shaped mounting portion provided at each end of the vibrating string, and having a mounting insertion hole formed therein;
A string vibrating body integrally configured with torsion prevention beams disposed on both sides of the vibrating string in parallel with the vibrating string, each end of which is connected to the mounting portion, the string vibrating body is operated by a string vibrating force. A string vibrator that is used by cutting off both ends of the anti-twisting beam and removing the anti-twisting beam from the mounting portion after being attached to a predetermined position of the detector. (2) The string vibrating body according to claim 1 of the utility model registration, characterized in that at least one small hole is bored along the cutting position at both ends of the torsion prevention beam to facilitate cutting. . (3) The string vibrating body according to claim 1, which is a utility model registration, characterized in that notches are formed at the cutting positions at both ends of the torsion prevention beam to facilitate cutting. (4) The string vibrating body according to claim 1 of the utility model registration, characterized in that a groove is formed on at least one surface of the torsion prevention beam along the cutting position at both ends thereof to facilitate cutting. .
