Title:
GROMMET
Document Type and Number:
Japanese Patent JP2014110747
Kind Code:
A
Abstract:

To provide a grommet that prevents decrease in mounting strength, in a case where a large hook portion cannot be formed on the peripheral edge of the through-hole of a panel to which the grommet is attached.

A grommet is molded from rubber or elastomer, is externally fitted on a wire harness, and is thereby attached to a through-hole made in a panel, which is a target mount member. The grommet has a large-diameter cylindrical part provided with an annular locking recessed part, which is fitted on the peripheral edge of the through-hole. A locking part is provided in such a manner that one of side walls sandwiching the bottom of the locking recessed part is projected out beyond the other opposite side wall, thereby making the locking part thick. In the locking part, the outer peripheral face of a body with the largest diameter is made continuous, via a radius part, with the projecting end of a panel locking face continuous with the side wall of the locking recessed part, and a seal lip, which is pressed to the panel, projects at the position of the outer end of the panel locking face, in which it reaches the radius part. The radius part of the locking part and the outer peripheral face of the body are set to dimensions so as to be brought into close contact with the inner peripheral face of the radius part of the panel and the inner face of a flat face part continuous with the inner peripheral face of the radius part.
