Kind Code:
A
Abstract:
To provide a waterproof device that improves workability when fitting into a pipeline port.SOLUTION: A waterproof device 100 includes: a packing body 101 made of an elastic body having a cylinder sized to be fitted in a gap between an inner peripheral surface P22 of a conduit port P11 and a cable C10; a slit that allows the cable C10 to be inserted into the cylinder of the packing body 101; and a hollow chamber 120 that expands a peripheral wall 110 of the cylinder of the packing body 101 by filling the inside with a filler. In the peripheral wall 110, in an outer peripheral portion 111, which is an outer peripheral side of the cylinder of the packing body 101, a first portion provided in a state extending in a circumferential direction of the cylinder of the packing body 101 and a second portion 111c provided in a state extending along the first portion and extending outward from the first portion are arranged in an axial direction of the cylinder of the packing body 101, and a first sealing material is provided along the outer peripheral surface of the first portion, which is the surface on the outer peripheral side.SELECTED DRAWING: Figure 3
