Claims

[Scope of utility model registration request]

Both ends of the glass tube are closed to form a sealed space, a substantially flat pinch seal portion is formed at at least one end, and the filament is arranged in the sealed space by a lead wire held embedded in the pinch seal portion. and a glass bulb having an engaging portion formed at a position at an appropriate distance from the base of the pinch seal portion on at least one side of the pinch seal portion, and a glass bulb holder that holds the glass bulb and is fixed to the cap. The glass bulb holding plate is made of a metal plate having spring elasticity and includes a pair of intermediate holding pieces and two pairs of side holding pieces formed substantially in contact with both sides of the intermediate holding piece. These presser pieces are arranged such that two pairs of presser pieces are sandwiched between a substantially rectangular space, and
The intermediate presser piece and the side presser piece are respectively cut and raised to opposite sides, and the pinch seal portion of the glass bulb is pressed by the pair of presser pieces on both sides, and the intermediate presser piece and the side presser piece are One end of the side presser piece is engaged with an engaging part formed on the pinch seal part, and the other end is engaged with the outer surface of the pinch seal part side of the sealed glass container that forms the sealed space for the glass bulb. A one-heat light bulb characterized by being in elastic contact.
