Abstract

Selon la présente invention, une partie de surface supérieure de couvercle 21 d'un couvercle de batterie 20 recouvre toute la surface d'une surface supérieure d'une batterie et d'une borne de batterie depuis le haut dans un état monté sur couvercle. Un élément de couvercle élastique 30b est fixé au couvercle de batterie et s'étend dans la direction de la largeur du véhicule de manière à croiser un câble 16a sur le câble 16a dans l'état monté sur le couvercle. Une partie d'insertion de câble 37 est installée dans une section de l'élément de couvercle élastique 30b, ladite section croisant le câble 16a dans l'état monté sur le couvercle. Dans l'état monté sur couvercle, une surface inférieure de l'élément de couvercle élastique 30, est élastiquement déformée le long d'une surface périphérique externe du câble 16a, et est collée au câble 16a depuis le dessus, ladite surface inférieure constituant la partie d'insertion de câble 37. Dans l'état monté sur couvercle, l'élément de couvercle élastique 30b recouvre la borne de batterie à partir d'une direction transversale dans laquelle s'étend le câble 16a.
