Abstract

Le but de la présente invention est de rendre possible le fait d'absorber une erreur entre l'emplacement de support d'un fil électrique par rapport à un site de fixation et l'emplacement de connexion d'une borne d'une section d'extrémité de fil électrique, tout en empêchant la présence d'eau entre le fil électrique et un support. Selon la présente invention, un fil électrique doté d'un support comporte : un fil électrique sur la section d'extrémité duquel une borne est fixée ; et un support. Le support est conçu de manière à pouvoir être fixé au site de fixation et de telle sorte qu'un trou de retenue à travers lequel le fil électrique peut passer et être installé est formé dans celui-ci. Dans un état dans lequel une section de joint interne, disposée sur au moins une partie dans la direction d'extension du trou de retenue, est en contact avec la périphérie externe du fil électrique, le fil électrique est supporté par rapport au trou de retenue de manière à être déplaçable dans la direction d'extension du trou de retenue.
