PURPOSE: To stabilize constantly the bending oscillation posture of a square pillar type oscillator by installing a connection part in a ridgeline part of the oscillator, connecting a subsidiary wire extended in the direction crossing the oscillator with the connection part, making the connection part a protruding line connection part having two sides. CONSTITUTION: A protruding line connection part 13 having two sides 12 oriented to cross at right angles with the extension direction of the subsidiary wire and the X-axis direction is formed in a subsidiary wire connection part of the ridgeline part 1a of an square pillar type oscillator 1 so that the sides 12 of the connection part are faced with a notch part 14. The connection of the subsidiary wire 2 with the connection part 13 in this constitution can be conducted by a method in which for example, a round rod shaped subsidiary wire 2 is pressed to the top face of the connection part 13 to bond them by welding. In the connection state like this, the subsidiary wire 2, in a form to have a flat cross-sectional shape, is stuck to the connection part 13 so that a fusion part in which the oscillator 1 and the subsidiary wire 2 are integrated with each other and a surface contact part in which they are brought into contact with each other exist. |
