Abstract

PURPOSE:To prevent the deformation of a base and also the breakdown of bulb by forming a concavity fittable to a key groove with high accuracy in order to make the round fixation of the base exact. CONSTITUTION:The bulb 18, having the key groove 20 formed along the axial direction of the bulb in the peripheral surface of the sealing portion 19, is covered with the base 21 in such a way as to cover the sealing portion 19 and the opening end of a position facing the key groove 20 of the base 21 is deformed by pressing. And, the sloped surface 17 is moved circularly in a sliding manner along the eyelet direction from the opening end side of the base 21 to form the concavity 23 fittable to the key groove 20 in the base 21, whereby permitting the bse 21 and the bulb 18 to be fixed to each other without allowing any mutual rotational displacement.
