この発明は、種々な電気的製品の部品として使

るものである。(Prior Art and Problems to be Solved by the Invention) In a conventional crystal resonator of this type, a protrusion 22 is formed below a glass layer 21, as shown in FIG. Then, the cap 23 distorts the protrusion 22 inwardly.
It is crimped around the outside. By the way, this protrusion 2
2 is formed below the glass layer 21 to prevent the glass layer 21 from being crushed when the cap 23 is pressed by electrical or mechanical means. However, the presence of such a protrusion 22 has the disadvantage that the height of the entire crystal resonator becomes elongated by the height of the protrusion 22. Therefore, the present invention proposes a crystal resonator that can be made smaller and shorter in height than conventional crystal resonators.

A flange 8 is formed at the lower end of the cap 4;
Similarly, on the outer periphery of the base 3 is a flange 1 corresponding to the flange 8 of the cap 4, and on the inside of the flange 1 is a generally inverted U-shaped cross section whose outer periphery is crimped and sealed to the lower inner periphery of the cap 4. The annular jetty part 2 is constructed by forming a frame part 7 in the center of a base 3, in which a glass layer 5 for supporting electronic components is formed.

を奏する。(Effects of the Invention) In the crystal resonator according to the present invention configured as described above, the outer circumferential surface of the jetty portion 2 having a substantially inverted U-shaped cross section formed in an annular shape on the base 3 is located at the lower inner circumference of the cap 4. The surface is crimped and sealed, and the pressure generated at that time is completely absorbed by the jetty portion 2 being distorted in the inner circumferential direction. The frame 7 formed at the center of the base 3 is not affected in any way, and therefore the glass layer 5 formed within the frame 7 is not crushed by the pressure during the fitting. In the crystal resonator according to the present invention, although the cap 4 can be fitted to the base 3 without crushing the glass layer 5, there is a conventional crystal resonator under the glass layer 5. Since there is no protrusion 22, the height can be shortened accordingly, and the crystal resonator as a whole can be miniaturized, which is a unique effect.
