０ａを覆つている。 The lamp housing 40 is provided with an opening 40a for replacing the bulb, so a rubber cover 41 is used to cover the opening 40a to prevent rainwater and cleaning water from entering.
Covers 0a.
上記のゴムカバー４１は、バルブ１に対する給
電用の導電部材を貫通せしめねばならない。 The rubber cover 41 described above must allow a conductive member for supplying power to the valve 1 to pass through it.
電気の良導体は一般に熱の良導体である。この
ため、第５図の公知技術においてゴムカバー４１

寿命が短かくなる。
A good conductor of electricity is generally a good conductor of heat. For this reason, in the known technique shown in FIG.
The conductive member 42 passing through the valve 1 is connected to the filament 5 of the bulb 1 via a conductive/thermal conductive member (the lead wire 7 and the terminals 15, 16), so it becomes hot during use. . Therefore, the rubber cover 41 in contact with the rubber cover 41 deteriorates due to heat and its useful life is shortened.
上記のゴムカバーが高温部材に直接触れないよ

なければならない。このように四角形の開口を設
けると角の部分に応力集中を生じてゴムカバーが
裂ける。 In order to prevent the above-mentioned rubber cover from coming into direct contact with the high-temperature member, it is conceivable to allow the insulating member 8 to penetrate through the rubber cover (see FIG. 4). but,
When such a configuration is adopted, as can be easily understood from FIG. 4, a square opening (corresponding to the cross-sectional shape of the insulating member 8) must be provided in the rubber cover (not shown). If a rectangular opening is provided in this way, stress will be concentrated at the corners and the rubber cover will tear.
本考案は上述の事情に鑑みて為されたもので、
その目的とするところは、ゴムカバーが熱劣化す

次に、前記公知例と異なる点について説明す
る。 Next, points different from the above-mentioned known example will be explained.
本例における絶縁部材５０は、円柱状に構成さ
れ、端子１５，１６を口金９に対して固定的に支
承している。 The insulating member 50 in this example has a cylindrical shape and supports the terminals 15 and 16 fixedly on the base 9.
本例の絶縁部材５０は耐熱性合成樹脂を用いて
射出成形してあり、電気及び熱について不良導体
である。 The insulating member 50 of this example is injection molded using heat-resistant synthetic resin, and is a poor electrical and thermal conductor.
第２図は上記実施例の断面図である。ゴムカバ
ー５１はランプハウジング４０の開口部を覆つて
