Claims

[Scope of utility model registration request]

A no-mouth metal fitting having a crushing part at the base of the glass container, in which a lead-in wire connected to a fiber in the glass container is sealed, and a terminal part consisting of the lead-out end of the lead-in wire on the surface of the crushing part. In the light bulb structure, the terminal part is made into a flat shape and bent into a chevron shape to form the electrode pressure contact part, the free end of the terminal part is made into a sliding contact part, and the base of the electrode pressure contact part is protruded from the surface of the crushing part. A baseless metal light bulb structure characterized in that a gap is provided between the intermediate part of the electrode press-contacting part and the surface part of the crushing part in contact with the protrusion.
