Grommet and wire harness

A wire harness comprising:

• a harness body;
• and
• a grommet protecting the harness body, wherein
• the grommet includes:
• a fitting body causing a circumferential edge of a through hole having a circular shape and provided in a wall body to be fitted into a fitting groove having an annular shape and provided in an outer wall, and causing the harness body routed along a hole axis of the through hole in a space inside the outer wall to be extracted from the space through a first extraction port having a circular shape and disposed at a first axial end and through a second extraction port having a circular shape and disposed at a second axial end;
• a first tubular body having a cylinder axis coaxial with an axis of the fitting body, projecting outward from a circumferential edge of the first extraction port, and causing the harness body in the space to be extracted through the tubular body;
• and
• a second tubular body having a cylinder axis coaxial with the axis of the fitting body, projecting outward from a circumferential edge of the second extraction port, and causing the harness body in the space to be extracted through the tubular body,
• the fitting body includes a tubular portion having an outer circumferential wall surface continuously connected to the fitting groove at a position closer to the first tubular body than the fitting groove in the outer wall, and gradually reduced in diameter as being away coaxially from the fitting groove, at least one rib rising from the outer circumferential wall surface of the tubular portion and extending on the outer circumferential wall surface at least from a position equal in diameter to the circumferential edge of the through hole to a radially outer end, and a locked portion disposed radially inside the rib, rising from the outer circumferential wall surface, and configured to be locked to an outer circumferential surface of the first tubular body when the first tubular body is shifted relatively to the fitting body along the cylinder axis toward the second tubular body, to suppress elastic deformation of the tubular portion or reduce elastic deformation amount of the tubular portion,
• the rib is shaped to enable elastic deformation of the rib in a circumferential direction of the outer circumferential wall surface, and
• the outer circumferential wall surface has a plurality of projection groups disposed at equal intervals in the circumferential direction, each projection group being constituted by the locked portion and a plurality of the ribs disposed radially outside the locked portion.
