PURPOSE:To decrease greatly the working processes for the fixture of the crystal bar as well as to increase the intensity of the shock resistance by inserting the end part of the crystal bar directly to the concavity provided to the plug substance and then fixing it. CONSTITUTION:Crystal bar 15 is fixed by providing ribbon-shaped metal material 18 to the concavity of plug substance 16 into a socket shape and then inserting the end part of bar 15 into the concavity directly. Furthermore, the plug-in part of a socket shape doubles the support of bar 15 and the electrode route. As a result, the working processes can be reduced greatly for fixture of the crystal bar, and at the same time the electrode route is shared for both the lead terminal and the crystal bar at the fixed area to omit any other conduction means. Also, the intensity of the shock resistance can be increased since the fixed area functions as the buffer to the shock. |
