Document Type and Number:
Japanese Patent JP2016056869
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a seal structure capable of securing sealability and facilitating insertion of a cable.SOLUTION: A seal structure 100 of this invention comprises: an outer casing 30a; and a grommet 6 having an insertion part 62 into which the outer casing 30a is inserted. The insertion part 62 comprises a wall part 622, an insertion hole 621 and a seal part 623. The seal part 623 seals the outer casing 30a in the inside of the insertion hole 621. The seal part 623 has a lip part 624 continuous in a circumferential direction. The lip part has a first protrusion 624a and a second protrusion 624b. The first protrusion 624a is protruded from an outer periphery side toward the center of axis O1 of the insertion hole and is brought into tight contact with the outer casing 30a. The second protrusion 624b has a height toward the center of an axis O1 of the insertion hole 621 from the outer periphery side, which is lower than the first protrusion 624a and is connected to the outer casing 30a. The first protrusion 624a and the second protrusion 624b are alternatively arranged in the circumferential direction.SELECTED DRAWING: Figure 8
