PROBLEM TO BE SOLVED: To provide a seal structure of a coupling device capable of preventing deterioration in durability of a seal member.SOLUTION: A seal device 54 of an electronic coupling device 2 includes an annular rubber 58 interposing between a coupling case 26 and a coupling cover 22 that are located on a front side in a fore-and-aft direction of a vehicle, and including an elastically deformable lip portion 58b; and a deflector 56 having one end attached to an outer circumferential portion 26A of the coupling case 26, including a protrusion 56c provided radially outward of an outer circumferential end 22a of the coupling cover 22, and including a closed portion 56b with which the lip portion 58b slidably contacts. By inclining the protrusion 56c upward from the front side to a rear side of the vehicle, a radial width B of a gap 59 on the rear side of the vehicle is made larger than a radial width A of the gap 59 on the front side of the vehicle. |
