The terminal fixing member 29 is made of resin, and the wall surface of the inner
従って、端末固定部材２９の内周部２９ａの壁面にチューブ２７の外周面が熱溶着により連続的にかつ水密に取り付けられることにより、端末固定部材２９とチューブ２７との防水がなされる。
Therefore, the terminal fixing member 29 and the tube 27 are waterproofed by attaching the outer peripheral surface of the tube 27 to the wall surface of the inner
一方、端末固定部材２９の外周部２９ｂには、周方向に凹部２９ｅが形成され、この凹部２９ｅには、Ｏリング等のシール部材３１が設けられている。端末固定部材２９を第１の筐体１３の貫通穴２１に係合させると、シール部材３１が貫通穴２１の内周面と、端末固定部材２９の凹部２９ｅとに周方向にわたって密着し、第１の筐体１３の貫通穴２１と端末固定部材２９との防水がなされる。 On the other hand, a concave portion 29e is formed in the circumferential direction on the outer peripheral portion 29b of the terminal fixing member 29, and a sealing member 31 such as an O-ring is provided in the concave portion 29e.

Next, a heat welding method between the terminal fixing member 29 and the tube 27 will be described with reference to FIG. As shown in FIG. 6 (a), the tube 27 is inserted into the inner
なお、本形態例では、端末固定部材２９の形状を図７に示すような形状とした。即ち、端末固定部材２９の第１テーパ部２９ｃと第２テーパ部２９ｄとの接続部分Ｊには、その周方向にわたって突起２９ｆを形成した。
In this embodiment, the shape of the terminal fixing member 29 is as shown in FIG. That is, the protrusion 29f was formed in the connection part J of the
更に、図８に示すように、チューブ２７の熱溶着される箇所には、その周方向にわたって、熱溶着時に溶融した樹脂が通る微小な穴２７ｆを形成した。
このような構成によれば、以下のような効果を得ることができる。
Furthermore, as shown in FIG. 8, a minute hole 27f through which the resin melted at the time of heat welding passes is formed in the circumferential direction of the tube 27 at the place where heat welding is performed.
According to such a configuration, the following effects can be obtained.
（１）第１の筐体１３の貫通穴２１に対して係脱可能な端末固定部材２９を用いることにより、低コストの防水構造が実現できる。また、端末固定部材２９とチューブ２７とを取りけた後に電気的接続線１９をチューブ２７に挿通することができるので、製造が容易である。 (1) By using the terminal fixing member 29 that can be engaged and disengaged with respect to the through hole 21 of the first housing 13, a low-cost waterproof structure can be realized. In addition, since the electrical connection line 19 can be inserted into the tube 27 after the terminal fixing member 29 and the tube 27 are removed, the manufacturing is easy.
（２）チューブ２７の防水性は、水は通さず、水蒸気は通す選択透過性を有することにより、第１の筐体１３内部の結露を防止することができる。
（３）端末固定部材２９、チューブ２７は樹脂製で、端末固定部材２９の内周部２９ａの壁面とチューブ２７の外周面との取り付けは、熱溶着であることにより、製造コストが安く、接着に比べ接着等に比べ、溶着直後に所望の取付強度を得ることができる。また、本形態例では、チューブ２７が連続多孔質構造である場合、溶着すると端末固定部材の内周部を形成する樹脂が溶融してチューブの空孔部に侵入する、所謂アンカー効果により簡単にかつ確実に結合することができる。
(2) The waterproofness of the tube 27 can prevent dew condensation inside the first housing 13 by having a selective permeability through which water does not pass and water vapor passes.
(3) The terminal fixing member 29 and the tube 27 are made of resin, and the attachment between the wall surface of the inner
（４）端末固定部材２９の内周面の壁面は、端末固定部材２９の端面から内部に行くに従ってその径が漸次小さくなる第１テーパ部２９ｃを有することにより、円錐状の加熱治具５１をチューブ２７の内部に挿通し、チューブ２７の外周面を端末固定部材２９の内周部２９ａの壁面に押し付けることにより、容易に端末固定部材２９の内周部２９ａの壁面にチューブ２７の外周面を周方向に沿って連続的に熱溶着することができる。
(4) The wall surface of the inner peripheral surface of the terminal fixing member 29 has the
（５）端末固定部材２９の内周部２９ａの壁面は、端末固定部材２９の一方の端部から内部に行くに従ってその径が漸次小さくなる第１テーパ部２９ｃと、端末固定部材２９の他方の端部から内部に行くに従ってその径が漸次小さくなり、第１テーパ部２９ｃと接続される第２テーパ部２９ｄとからなることにより、熱溶着される箇所は第１テーパ部２９ｃと第２テーパ部２９ｄとの接続部分Ｊとなり、熱溶着される位置のばらつきがなくなる。
(5) The wall surface of the inner
（６）第１テーパ部２９ｃと第２テーパ部２９ｄとの接続部分Ｊには、その周方向にわたって突起２９ｆが形成されていることにより、熱溶着される箇所は突起２９ｆとなる。そして、熱溶着した場合、加熱治具５１が突起２９ｆに第１テーパ部２９ｃより先に接触して、溶けた材料が突起２９ｆの基部方向に逃げることができ、加熱治具５１が第１テーパ部２９ｃで止まることができるので、多少の第１テーパ部２９ｃの寸法精度が悪くても、確実な熱溶着を得ることができる。
(6) Since the projection 29f is formed in the connection part J of the
（７）チューブ２７の熱溶着される箇所には、その周方向にわたって、熱溶着時に溶融した樹脂が通る微小な穴２７ｆを形成したことにより、熱溶着時に溶融した樹脂がチューブ２７の内周まで行き渡り、溶着強度が向上する。 (7) By forming the minute hole 27f through which the resin melted at the time of heat welding passes in the circumferential direction of the tube 27 at the location where the heat is welded, the resin melted at the time of heat welding reaches the inner periphery of the tube 27. Spread and improve welding strength.
尚、本発明は、上記形態例に限定するものではない。上記形態例は第１の筐体１３の防水構造で説明したが、第２の筐体１５の防水構造にも適用できる。さらに、本発明の防水構造は、折り畳み電子機器以外の電子機器にも適用できることは言うまでもない。 The present invention is not limited to the above embodiment.
