To provide a sealing structure excellent in sealing function and sound insulation performance.SOLUTION: A dust seal 50 provided on a vehicle door lower edge part and a door weather strip 10 lower part comprises: a mounting base part 51 mounted on a first inclined face 1a of a door 1; and a hollow seal part 52 disposed in elastic contact with a periphery of a corner part R1 between a first vertical face 2a and a first inclined face 2b. The hollow seal part comprises: a first vehicle-inside inclined wall 521 extending downward on vehicle inside from vehicle inside of the mounting base part and a second vehicle-inside inclined wall 522 bent toward vehicle outside from the former vehicle-inside inclined wall, extending obliquely downward on vehicle outside, and protruding and bending downward; and a first vehicle-outside inclined wall 523 extending downward on vehicle outside from vehicle outside of the mounting base part and a second vehicle-outside inclined wall 524 bent toward vehicle inside from the former vehicle-outside inclined wall, extending obliquely downward on vehicle inside, and connected to the second vehicle-inside inclined wall 522. The hollow seal part has a sealing lip part 53 extending downward on vehicle inside from the second vehicle-outside inclined wall 524 and brought into elastic contact with the first vertical face 2a when the door is closed.SELECTED DRAWING: Figure 1
