Abstract: A grommet includes: an enlarged-diameter cylindrical portion that has a fitted groove that is around a larger-diameter-side peripheral portion and is configured to be fitted to a through hole of a panel, and an elastically deformable portion that extends from the larger-diameter-side peripheral portion to a smaller-diameter-side peripheral portion and is elastically deformable; and a smaller-diameter cylindrical portion that is configured to be connected with the smaller-diameter-side peripheral portion of the enlarged-diameter cylindrical portion, and in which a wire harness is inserted. A reinforcement rib protrudes from an interior surface of the elastically deformable portion of the enlarged-diameter cylindrical portion. The reinforcement rib is T-shaped. The reinforcement rib has depressions for deformation. The depressions for deformation face in the opposite directions. An intersection of the reinforcement rib that is T-shaped is between the depressions for deformation.

Abstract: There is provided a protector to be assembled and fixed to a given position of a fixation object. The protector includes an accommodating space and an opening consecutive to the accommodating space which an electric wire or a bundle of electric wires is adapted to be passed through and accommodated in. The accommodating space includes an excessive part accommodating space which accommodates an excessive part of the electric wire or the bundle of electric wires.
