<p>PROBLEM TO BE SOLVED: To provide a rubber sleeve, which the installation to a box and the like is easy and has excellent properties of water proof, dust proof and oil proof. SOLUTION: The rubber sleeve has a sleeve main part 2 which is formed with the outer peripheral surface of a conical tapered shape and possible to fit into an electric wire pull-in opening 21 of the box and the like and has a single or a plurality of electric wire passing holes 3 and a sealing member 4 which is a skirt-like member connected to the end of the sleeve main part 2 at the larger diameter side and possible to fold back toward the smaller diameter side of the sleeve main part. Invasion of water, dust, oil is surely prevented by dual sealing effect of the seal by folding back the sealing member 4 and the seal by adhesion between the outer peripheral surface of the sleeve main part 2 and the inner peripheral surface of the electric wire pull-in opening 21.</p> |
