WATERPROOF STRUCTURE FOR ELECTRIC WIRE CONNECTION

摘要

A waterproof structure for an electric wire connection is provided with: an electric wire connection in which core wires exposed from end parts of insulating coverings on a pair of electric wires are electrically connected to each other; a cylindrical member that covers altogether the electric wire connection and the end parts of the insulating coverings of the pair of electric wires; an inner layer provided in the cylindrical member and having ring-shaped ribs that protrude in a ring shape toward the inside and elastically adhere to the outer periphery of the insulating coverings of the pair of electric wires; and an outer layer, which is formed from a material with a higher hardness than the inner layer and is provided so as to overlap the outer periphery of the inner layer.
