Device for fitting headlight with a lamp

Abstract

A device for fitting a vehicle headlight with a lamp includes a flange receiving portion for receiving a bayonet flange of the lamp, three recesses formed on the flange receiving portion for receiving three outer pawls radially projecting from the bayonet flange, and a substantially circular retainer spring made of a piano wire, a stainless steel wire or the like and adapted to be fastened to the flange receiving portion by threadably tightening three screws. Three substantially U-shaped retaining portions are formed along the retainer spring in an equally spaced relationship when viewed in a circumferential direction so as to enable each outer pawl to be firmly clamped between a bottom of each recess and a corresponding retaining portion of the retaining ring. When the lamp is fitted in the headlight, it is turned to a predetermined insertion position from the initial position wherein the outer pawls are initially received in the recesses formed on the flange receiving portion. To assure that the outer pawls of the bayonet flange are firmly held on the flange receiving portion without any necessity for threadably tightening screws, the outer pawls may be received in fitting slits that are provided between a plurality of slantwise upwardly extending projections and the bottom surfaces of the recesses formed on the flange receiving portion with the exception of one outer pawl. The slits have a substantially U-shaped retaining portion of the substantially circular retainer spring positioned thereon. Each of the slantwise upward extending projections is integrally formed with the flange receiving portion.
