Abstract

An object is to provide technology that can reduce the thickness of an inlet assembly. A grommet includes a main body portion that covers an inlet installed in a vehicle and a wiring member extending from the inlet. The main body portion includes a connection port through which a connecting portion of the inlet to be connected to an external charging connector is inserted and an outlet port through which the wiring member is inserted. The connection port is open in a first direction, and the outlet port is open in a second direction that intersects the first direction.

First claim

What is claimed is:

1 . A grommet comprising:
a main body portion configured to cover an inlet installed in a vehicle and at least one wiring member extending from the inlet, wherein
a connecting portion of the inlet is configured to be connected to an external charging connector, and
the main body portion includes
a connection tube portion extending in a first direction and including an internal space that serves as a connection port through which the connecting portion is inserted, the connection port being open in the first direction;
a lip portion having an annular shape and being formed on an inner surface of the connection tube portion, the lip portion configured to come into contact with an outer surface of the connecting portion when the main body portion covers the inlet; and
at least one outlet port through which the at least one wiring member is inserted, the at least one outlet port being open in a second direction that intersects the first direction.

2 . The grommet according to claim 1 , wherein
the main body portion further includes a water drain port for discharging water that has intruded into the main body portion, and the water drain port is open in a third direction that intersects the first direction and the second direction.

3 . The grommet according to claim 2 , wherein
the main body portion further includes a partition that overlaps the water drain port as viewed in the third direction, and the partition is arranged between the water drain port and a space where the at least one wiring member is arranged inside the main body portion.

4 . The grommet according to claim 2 , wherein the main body portion further includes a water drain tube portion extending in the third direction and including an internal space that serves as the water drain port.

5 . The grommet according to claim 1 , wherein
the main body portion further includes an outlet tube portion extending in the second direction and including an internal space that serves as the at least one outlet port, and a ring-shaped lip portion capable of coming into contact with the at least one wiring member is provided on an inner surface of the outlet tube portion.

6 . The grommet according to claim 1 , wherein
the lip portion is formed such that an area encompassed by the lip portion is smaller than an area defined by the outer surface of the connecting portion, and the lip portion includes at least one lip formed over an entire circumference on the inner surface of the connection tube portion.

7 . The grommet according to claim 1 , wherein
the at least one outlet port includes a plurality of outlet ports, and the at least one wiring member includes a plurality of wiring members.

8 . An inlet assembly comprising:
the grommet according to claim 1 , wherein
the connecting portion extends to the outside of the grommet via the connection port, and
the at least one wiring member extends to the outside of the grommet via the at least one outlet port.

9 . An inlet assembly comprising:
the grommet according to claim 7 , wherein
the connecting portion extends to the outside of the grommet via the connection port,
the plurality of wiring members extend to the outside of the grommet via the plurality of outlet ports, and
the plurality of outlet ports include at least one outlet port through which only one wiring member of the plurality of wiring members is inserted.

10 . The grommet according to claim 6 , wherein the at least one lip includes a plurality of lips spaced apart from each other in the first direction.
