口１d-1を設けた蓋状の部材である。 The halogen bulb 1 is airtightly fitted into a cylindrical mounting portion 2a provided at the rear of the reflector 2 via an O-ring 8. This halogen bulb 1 has a pinch seal portion 1a formed at the rear end of the glass tube portion, and this pinch seal portion 1a is exposed into a cylindrical holder 1b, which is filled with heat-resistant cement 1c and made into individual pieces. 1d is a lid-like member provided with an opening 1d -1 larger than the pinch seal portion 1a.

おかなければならず、作業性が極めて悪いという
問題がある。 The conventional halogen bulb mentioned above has a structure in which the glass tube part is fixedly supported using heat-resistant cement, so special equipment is required to harden the heat-resistant cement, and the assembly process is time-consuming. Since it takes some time to harden in the middle, it has to be left alone during that time, which poses a problem of extremely poor workability.

生じるという不都合もある。 In addition, after the heat-resistant cement hardens, it absorbs moisture from the atmosphere and is affected by humidity, so if you attach the assembled halogen bulb to the lamp as is,
There is also the disadvantage that when the halogen bulb d is turned on, cloudiness occurs inside the lamp chamber.

困難である。 In order to eliminate the troubles caused by heat-resistant cement as described above, for example, the lid-like member 1d in the conventional example shown in FIG. 1 is fixed to the holder 1b, and the opening 1d -1 of the lid-like member and the pinch seal portion 1a It is also conceivable to tightly fit the glass tube parts and firmly support the glass tube part without using heat-resistant cement. However, if the structure is such that the glass tube part is fixedly supported by a rigid member as in the above-mentioned proposal, the filament 1e sealed in the glass tube part is held in the holder 1b.
It is difficult to adjust to a predetermined position.
