Abstract

A grommet includes a hollow grommet main body, a protector placed in a hollow space of the grommet main body, and an outer member for fixing the grommet main body to an attachment surface. The grommet main body has a first grommet-main-body-side recess to engage with a protector-side projection of the protector, and a second grommet-main-body-side recess on an outer wall surface of the grommet main body to be adjacent to the first grommet-main-body-side recess. The outer member has an outer-member-side projection engaged with the second grommet-main-body-side recess. The protector-side projection and the outer-member-side projection are located to sandwich a portion of the grommet main body in a direction crossing to a pressing direction of the outer member when the protector is placed in the hollow space and the grommet main body being fixed to the attachment surface by the outer member.

First claim

The invention claimed is:

1. A grommet comprising:
a hollow grommet main body comprising an elastic material and having an outer surface to enable a water stopping between an attachment surface and the grommet main body;
a protector placed in a hollow space of the grommet main body; and
an outer member for fixing the grommet main body to the attachment surface while pressing the grommet main body against the attachment surface,
the protector having: a deep-side end portion located in a deep-side area of the hollow space; an opening-end-side end portion located in an opening-end-side area of the hollow space; and a protector-side projection engaged with the grommet main body upon the protector being placed in the grommet main body,
the grommet main body having: a first grommet-main-body-side recess on an inner wall surface of the grommet main body to engage with the protector-side projection; and a second grommet-main-body-side recess on an outer wall surface of the grommet main body to be adjacent to the first grommet-main-body-side recess, while eliminating a structure to exert a preventive force to the opening-end-side end portion for preventing separation of the protector from the grommet main body,
the outer member having an outer-member-side projection engaged with the second grommet-main-body-side recess,
the protector-side projection and the outer-member-side projection being located to sandwich a portion of the grommet main body in a direction crossing to a pressing direction of the outer member upon the protector being placed in the hollow space and the grommet main body being fixed to the attachment surface by the outer member.

2. The grommet according to claim 1 , wherein
the protector-side projection is formed to extend in the pressing direction, and
the outer-member-side projection is formed to extend in the pressing direction.

3. The grommet according to claim 1 , wherein
the hollow space of the grommet main body has a bent portion to have a bent shape,
the protector has: a first protector portion extending toward one side from the bent portion along the shape of the hollow space; and a second protector portion extending toward the other side from the bent portion along the shape of the hollow space,
the protector-side projection has a rib shape connecting an outer wall surface of the first protector portion and an outer wall surface of the second protector portion.
