Claims

[Scope of utility model registration request]

U equipped with a cap with a pair of protrusions around the periphery
A lamp fixing fitting for a lighting fixture that removably holds a letter-shaped fluorescent lamp is constructed by integrating a mounting fitting made of a plate member and a leaf spring fitting made of a leaf spring member, and is a circular lamp fitting into which a base is inserted into the fitting. A hole is provided, and the circumference of the round hole includes an insertion recess through which the protrusion of the cap is inserted, a locking protrusion of the cap protruding from the lamp rotation side of the insertion recess, and a cap protruding from the lamp reverse rotation side of the insertion recess. A pair of anti-rotation protrusions are provided facing each other at the center, and the plate spring fitting is formed into a ring shape with an inner diameter approximately the same as the round hole of the mounting bracket into which the cap is inserted, and the protrusion of the cap is inserted into the inner diameter side. A pair of notch recesses are provided facing each other,
A tapered part is formed that gradually increases in height from this notched concave part toward the lamp rotation side, and following this taper part, a cap convex part is formed whose height including the mounting bracket is larger than the dimension from the base of the base to the convex part. A lamp fixing device for a lighting device, characterized in that a locking fixing recess is formed, and an end of a flat portion continuously formed in the fixing recess is connected to a flat portion provided on the reverse rotation side of the lamp in the notched recess. Metal fittings.
