  • Patent number: 9896042
    Abstract: A grommet includes a bellows portion and a movable-member-side fitting portion connected with an end of the bellows portion. The movable-member-side fitting portion has an outer surface connected with the bellows portion and an inner surface formed on the opposite side of the outer surface. On the outer surface, the bellows portion is connected to the movable-member-side fitting portion with unequal distances from an axial center of the bellows portion to the outer edge of the movable-member-side fitting portion. Furthermore, on the outer surface, a first outer rib is formed that extends along a direction having a maximum distance from the axial center to the outer edge with an outer peripheral surface of the bellows portion serving as its base.
