  • Patent number: 11215002
    Abstract: A sealing structure includes a sliding door, a touch sensor, an inner seal, a drip seal, a buffer, and a projection. The inner seal couples to a door opening. The drip seal extends in a front and rear direction of an automobile body, is above the door opening, and is closer to an upper part of the automobile body than the inner seal. The drip seal and the inner seal make elastic contact with the sliding door. The buffer extends in an upper and lower direction of the automobile body and protrudes outwardly. The buffer is provided on a part of a body panel, which is closer to a front part of the automobile body than the door opening, and faces and is close to a flange when the sliding door is in a closed position. The projection extends from the touch sensor and makes elastic contact with the buffer.
