A grommet includes a water stop part having an annular shape that stops water by being inserted into a through hole formed on a mounting panel, and a first partition wall part or a second partition wall part disposed so as to close the annular shape of the water stop part by extending in a radially inner side of the water stop part. The water stop part includes an abutting surface formed in an annular shape capable of coming into contact with one side of a peripheral part of the through hole in an axial direction, and a plurality of claw parts that face the abutting surface in the axial direction, that are capable of coming into contact with another side of the peripheral part of the through hole, and that are intermittently provided in a circumferential direction.

Water-stop grommet and wire harness

A grommet includes a main body that fits into a through hole penetrating an attachment target in an axial direction to waterproof the through hole and that allows a wiring member to be inserted into an inner portion in the axial direction. The main body includes a plate-shaped portion extending in intersecting directions that intersect the axial direction so as to close at least a portion of the through hole, and a sound insulation wall portion having a sound insulation protrusion that protrudes from the plate-shaped portion in the axial direction so as to be formed in an annular or arc shape centered around a central axis in the axial direction.

Grommet and wire harness

A grommet includes an inner side harness insertion portion extending toward an inner side of a vehicle, an outer side harness insertion portion extending toward an outer side of the vehicle, a lip mountain base integrated with the inner side harness insertion portion, a lip mountain integrated with the lip mountain base, a panel abutment portion abutting on a periphery of the through hole in an outer side surface of a vehicle body panel, a connection portion connecting the lip mountain and the panel abutment portion, a work unit formed across the outer side harness insertion portion and the panel abutment portion, and a work pressing portion integrated with the outer side harness insertion portion and the work unit. A plurality of recesses are formed between facing surfaces of the work pressing portion and radially arranged about a central axis of the outer side harness insertion portion.

Grommet

In a locking structure for a clamp, the clamp is formed with a projecting component to be fixed to a counterpart member through a through hole of the counterpart member via locking wings. A base plate section is equipped with a coupling step section which can engage the through hole and contact the entire inner peripheral surface of the through hole Pa. The locking structure can prevent the clamp from rotating by making the through hole of the counterpart member in an elongated shape while making the base in an elliptical shape.
