Abstract

PURPOSE:To improve an impulse-proof property of a crystal vibrator by storing a crystal oscillation piece, where a molding part is provided in the tuning fork arm part in the face parallel with the tuning fork face of the crystal oscillation piece, in an enclosed vessel which has no part parallel with the tuning fork plane in the inside circumference face. CONSTITUTION:A molding part is provided at the tip of the tuning fork of thin plane-shaped tuning fork crystal oscillation piece 4 which is subjected to the outline pulling-out process by etching, and this oscillation piece 4 is enclosed in vacuum in vessel 2 where the inside circumference form has no face parallel with the tuning fork plane and the sectional form is round or elliptic. At this time, since gap d between the tip of crystal oscillation piece 4 and the inside wall of vessel 2 in the Y direction is large, the tuning fork arm part is difficult to strike the vessel inside by gap components. Then, since the tangent line angle at the strike point of the arm part tip in the vessel inside wall is small, propability that two tuning fork arms strike the vessel inside wall separately is reduced considerably.
