As explained above, according to the present invention, the circuit board
Even if it is made of a rigid material such as a PCB, the entire circuit device made of that rigid material is held by an elastic member, so even if a large impact is applied from the outside, the elastic member will not deform. The shock to the circuit device is greatly alleviated, and the circuit device itself can be deformed much more freely than when the circuit device is directly fixed with screws, allowing for sufficient displacement for shock absorption. Therefore, a large buffering effect can be obtained.

きる。 Furthermore, since there is a gap between the crystal oscillator and the substrate (base plate), no direct impact is applied to the crystal oscillator. Furthermore, electronic components other than the crystal resonator, such as temperature compensation capacitors that are susceptible to shock, can be protected from shock at the same time, and other great effects can be obtained.
又、弾性部材が回路装置と一体にできる場合に
は更に構造が簡単となる上、組立作業性も良好で
ある等の効果を有する。 Further, when the elastic member can be integrated with the circuit device, the structure is further simplified and the assembly workability is also improved.
