る。According to the present invention, even if the terminal body is formed in a small size by making the protruding amount of the protruding portion of the base piece portion shorter than the length of the base terminal pin contacting piece portion and the connecting piece portion, the fluorescent lamp can be formed. If the bending force between the base piece and the base terminal pin contact piece and the bending portion between the base piece and the connecting piece are elastically deformed by the pressing force of the base terminal pin when mounting the The tip abutting portion of the terminal pin contact piece portion abuts the projecting portion of the base piece portion, and deformation of the bent portion between the base piece portion and the base terminal pin contact piece portion is suppressed,
The bent portion of the protruding portion is elastically deformed, the stroke within the elastic range of the terminal body is increased, the repulsive force at the time of mounting the base terminal pin can be reduced, and the operation feeling can be improved.
The connection piece of the terminal body is connected to the circuit board that closes the opening of the terminal body storage chamber, the connection between the terminal body and the lighting circuit is easy, the assembly is easy, and the lock piece that connects to the lead wire, etc. The terminal body is small in size in combination with shortening the protrusion of the base piece, and the structure is simple and can be obtained at low cost.
