本考案は、シールドタイプの前照灯に装着する
ハロゲンバルブに関するものである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a halogen bulb installed in a shield type headlamp.
第１図はこの種のハロゲンバルブの従来例を示

内に臨ましめ、耐熱セメント１ｃを充填、固化せ
しめてある。１ｄは、ピンチシール部１ａよりも
大きい開口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 2a- 1 . This halogen bulb 1 has a pinch seal part 1a formed at the rear of a glass bulb G, and this pinch seal part 1a is held in a cylindrical holder 1b.
The inside of the container was filled with heat-resistant cement 1c and allowed to solidify. 1d is a lid-like member provided with an opening 1d- 1 larger than the pinch seal portion 1a.

造であるから、該耐熱セメントを硬化させる為の
特殊な装置が必要になり、しかも組立工程の途中
で硬化する時間を要するので、その間放置してお
かなければならず、作業性が極めて悪い。 The conventional halogen bulb described above has a structure in which the glass bulb 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 time to harden in the middle, it must be left alone during that time, making workability extremely poor.

ハロゲンバルブの点灯時、灯室内部にくもりが生
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 light fixture,
There is also the inconvenience that when the halogen bulb 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 are
It is also conceivable that the glass tube portion be fixedly supported without using heat-resistant cement by tightly fitting the two. However, if the structure is such that the glass tube is fixedly supported by a rigid member as in the above-mentioned proposal, the filament 1e sealed in the glass tube will be held in the holder 1b.
It is difficult to adjust to a predetermined position.

In order to achieve the above object, the halogen bulb for headlights of the present invention comprises an adapter that connects a resin cylindrical holder and a glass bulb, and the adapter is attached to the pinch seal portion of the glass bulb. A cylindrical part fitted and fixed on the outside and leg-shaped tongues loosely fitted into the cylindrical holder are integrally connected, and the leg-shaped tongues are inserted into the cylindrical holder, and the Align the filament provided on the glass tube within the range of play, and with the filament in place, fill the above-mentioned cylindrical holder with a fixing agent and let it harden to fix the tongue piece of the adapter. It is characterized by what it did.
次に、本考案の１実施例を第２図及び第３図に
ついて説明する。
Next, one embodiment of the present invention will be described with reference to FIGS. 2 and 3.

ように構成すれば良い。 The pair of tongue pieces 3b in this embodiment is configured in a conical shape, and as shown in FIG.
This structure is such that when the lower end portion of the cylindrical holder 1b is inserted into the cylindrical holder 1b, the rectangular cylindrical portion 3a protrudes above the cylindrical holder 1b. When implementing the present invention, the shape of the tongue piece does not necessarily have to be conical, but can be arbitrarily configured such as pyramidal or prismatic. In short, the leg-like tongue piece of the present invention has a leg-like configuration that supports the cylindrical part fitted into the pinch seal part of the glass tube, and is designed to be able to fit loosely into the cylindrical holder. It should be configured as follows.

In this example, four leg-shaped tongue pieces 3b- 1 are provided. The four leg-like tongue pieces 3b- 1 can be configured parallel to each other, but if they are shaped with open ends as in this example, the fixed state becomes stronger.
