Patent attributes
A grommet includes a fitting body causing a circumferential edge portion of a through hole provided in a wall body to be fitted into a fitting groove provided in an outer wall, and a first cylinder and a second cylinder causing a harness body to be extracted through the cylinder. The fitting body includes a cylindrical portion, a plurality of ribs rising from an outer circumferential wall surface of the cylindrical portion and disposed on the outer circumferential wall surface at equal intervals in a circumferential direction, and a first support portion and a second support portion provided for each of the ribs. The first support portion and the second support portion project from the outer circumferential wall surface to be high enough to suppress elastic deformation of the rib in the circumferential direction toward the outer circumferential wall surface.
