It is formed side by side along the axis 0 of the rotation axis 2, and even these straight 5 B and 5 B are arranged side by side to form two rows side by side on the axis 0 of the rotation shaft 2 to form a total of four front end portions 5 B. And the opening-side end surface of the groove portion 3 B of the side wall 3 C and 3 C of the vibrator 3 is pressed downward and formed two recesses along the axis 0 direction respectively, so that the inner surface of the groove portion 3 B and the rotation axis 2 close together, the vibrator 3 and the rotating shaft 2 will be integrated together. As described above, the invention described in any one of claims 1 to 2 is a groove portion forming a fitting rotation shaft, and the opening-side end surface I of the groove portion located on the side wall forming the groove portion is directed from the opening side of the groove portion toward the bottom Squeeze the relationship between the rotating shaft and the vibrator as a whole. It is not necessary to ensure that the paper size is in accordance with the Chinese National Standard (CNS) A4 (210 X 297 mm) -13-d6 3 45 〇A7 B7 V. Description of the invention (11) Required binding force | When the side wall is plastically deformed and bent on the side of the rotation axis, the upper end of the side wall is covered on the upper part of the rotation axis. The eccentric load can effectively work and improve the vibration efficiency. And it will not be affected by the bending stress of the side wall as it is known ', so it can not only prevent the vibrator from generating cracks, but also increase the content of tungsten (W) without considering any toughness, and achieve a high specific gravity of the vibrator. These results make it possible to reduce the size and weight of the vibrator, and further reduce the size, weight, and cost of the entire vibration generator and small wireless device. Furthermore, since the end faces on the opening side of the groove portion formed on both side walls of the groove portion are squeezed and squeezed, the entire side wall is not plastically deformed and bent as is conventionally known, and therefore there is an advantage that the tightening load is smaller than conventionally. According to the invention described in claim 2, the groove portion of the vibrator is formed with the center angle of the rotation axis within a range of 180 ° or more1, so that the rotation axis can be reliably restricted to pass through the groove portion of the vibrator. This makes these bonding strengths have a higher effect. [Brief description of the drawing] Figure 1 is a plan view of the vibrator in the first embodiment of the present invention.
