摘要： A piezoelectric vibrator is housed in a case (10), the opening of the case (10) is sealed with a base (18). The base (18) of a columnar body having an elliptic or nearly elliptic cross section perpendicular to the axis of the case (10) at the part which comes into contact with the case (10). The case (10) is a tubular body having a cross section whose inner periphery is elliptic or nearly elliptic and smaller than that of the base (18) and which is perpendicular to the axial direction at the part which comes into contact with the base (18) and has a closed end and an open end. The base (18) is press-fitted to the open end of the case (10) to seal the vibrator. The press-fitting allowance is such that it is maximum between the minor and major axes of the elliptic or nearly elliptic cross section.

摘要： A base (10) is provided with a plug (12) having a substantially cylindrical shape and two lead wires (14) passed through the plug (12). A piezoelectric vibrating body (24) is fixed to the front ends of the lead wires (14) with a supporting member (26) composed of a soldering material containing lead with the ratio of more than 60 wt.%, preferably 85-98 wt.%. A cap (28) which is opened on one side is put on the vibrating body (24). The cap (28) forms an airtight container when the opened end is sealed with the plug (12) and, also, a piezoelectric vibrator airtightly housing the vibrating body (24). Since the solder containing a high percentage of lead is soft and low in Young's modulus, the solder disperses stresses when shocks are applied to the piezoelectric vibrator. Therefore, the concentration of stresses to the vibrating body (24) can be avoided and the shock resistance of the piezoelectric vibrator can be improved. In addition, since layers of solder containing
摘要翻译：基座（10）设置有具有基本上圆柱形形状的插头（12）和穿过插头（12）的两根引线（14）。一个压电振动体（24）用一根由含铅量大于60％（重量），优选为85-98％（重量）的焊料组成的支撑件（26）固定到引线（14）的前端％。将一侧开口的盖（28）放在振动体（24）上。当开口端用插头（12）密封时，盖（28）形成气密容器，以及气密地容纳振动体（24）的压电振动器。由于含铅量高的焊料柔软且杨氏模量低，所以当冲击施加到压电振动器时，焊料会分散应力。因此，可以避免对振动体（24）的应力集中，并且可以提高压电振动器的抗冲击性。此外，由于在引线（14）的表面上形成含有
