PURPOSE:To hold always a rectangular crystal bar with high stability and high impact resistance, by using a dogleg metallic holder and an L-shaped metallic holder having a dogleg part. CONSTITUTION:A metallic holder 12 an end fixed to an inner terminal 14 and the other end folded into a dogleg shape is provided to the base 15. At the same time, an L-shaped metallic holder 8 having an end fixed to an inner terminal 16 and the other end folded into a dogleg shape is provided. The both ends of a crystal bar 17 are attached to the dogleg parts of holders 8 and 12. The folding angle theta of the dogleg part is decided by the forms of both ends of the bar 17. In such a way, the crystal bar 17 can always be held with high stability and high impact resistance. |
