Abstract: PURPOSE:To improve the productivity by moving a reed piece to a contact gap, and stopping the movement when the contact is absorbed, in a glass tube. CONSTITUTION:The end of a glass tube 4 at a reed piece 3 side is heated and sealed by a torch 15. A chuck 11 holding the reed piece 2 is moved to separate between contacts 2a and 3a sufficiently, and then, a coil 21 to generate a magnetism to get a working value corresponding to the desire of a customer is provided. Then, the chuck 11 is moved in the inverse direction to reduce the gap between the contacts 2a and 3a gradually, and it is stopped at the absorbed and contacted time of the gap. Then, the current feeding to the coil 21 is released to form a necessary contact gap DELTA, and the end at the reed piece 2 side is heated and sealed by the torch 15 while pouring an inert gas. Since the fluctuation causes of working value owing to the contact gap variations from the inclination of the reed piece 3 at the sealing, or the quality, the form, the plating thickness, and the like of the reed piece 3 itself, are all incorporated in the gap DELTA, the product can be responded to the desire of the customer in a stable condition, and the productivity can be improved.
