Claim 0:
1. A grommet comprising:
a cylindrical base part having a cylindrical shape which covers an outer peripheral side of a steering shaft passing through a shaft through hole formed by penetrating a dash panel of a vehicle body which partitions between a vehicle cabin and an engine room;
a flexible part provided so as to be expanded outward in a radial direction of the cylindrical base part from an axial end portion of the cylindrical base part, so as to be axially and flexibly deformed; and
a seal portion provided to a distal end portion of the flexible part so as to come in contact with a vehicle outside hole edge of the shaft through hole in a state of being attached to the vehicle body,
wherein the flexible part includes a first flexible portion provided so as to extend outward in the radial direction of the cylindrical base part from the axial end portion of the cylindrical base part, and a second flexible portion provided so as to extend in a curved shape on a seal portion side from the first flexible portion, and having a bending portion which is axially bendable,
wherein a padding portion is provided on an outer side of the second flexible portion such that a thickness of the second flexible portion is thicker than that of the first flexible portion,
wherein the grommet is attached such that the seal portion obliquely comes in contact with the dash panel, and
wherein, in a circumferential area of the second flexible portion, the padding portion is provided only in an area located on a grommet attachment direction side from a grommet attachment direction orthogonal line which passes through a center of the seal portion and which is orthogonal to a grommet attachment direction.
