があった。However, in the above-mentioned structure, the metal base 3 is moved up and down, for example, as shown in FIG. 6 by the pressing force at the time of resistance welding between the metal base 3 and the metal cover 4. It deforms and gives distortion to the crystal blank 2 via the supporter 8 (ab). Therefore, before and after sealing, there is a problem that the oscillation frequency changes due to stress sensitivity characteristics and the like. For this reason, for example, as shown in FIGS. 7 and 8, a rectangular through groove 12 is provided at the center of the supporter 8, or a cutout 13 (ab) is provided on both sides.
Some have tried to absorb the impact of resistance welding by providing flexibility. However, in each of these,
Since the connecting portion is linear, there has been a problem that the impact absorption efficiency is poor.
