PURPOSE: To fit an electric bulb regardless of its shape and improve flexibility by providing an elastic section on part of the inner pawl of a holder section, and integrating an electric bulb fitting section and the holder section.

CONSTITUTION: Electric bulb reception sections 2a are provided on the inner peripheral side of an electric bulb insertion section 2 in the shape that the flange 4b of an electric bulb 4 is fitted, and hook pawls 2b are provided at three positions on the outer peripheral side. An inner pawl 3d protruded inward is provided on each of protrusion sections 3c provided on the outer peripheral section of an opening section 3b, and two slits 3e are provided at the interval nearly equal to the pawl width of the hook pawl 2b over a cylindrical section to perpendicularly split part of the inner pawl 3d, and an elastic section 3f is formed. When the hook pawls 2b and the elastic sections 3f are faced to each other and pressed, the elastic section 3f are deformed and hooked on the hook pawls 2b, and the electric bulb fitting section 2 and a holder 3 are integrated.
