Abstract
A grommet includes a larger-diameter tubular portion for being fixed to a through hole, a smaller-diameter tubular portion for passing a wire therethrough, a shield wall of a conical wall-shape interconnecting the larger-diameter tubular portion and the smaller-diameter tubular portion, and a noise-insulating wall joined to an outer peripheral surface of the smaller-diameter tubular portion and flaring into a conical wall-shape. When the smaller-diameter tubular portion is displaced in a direction toward the distal end thereof, an outer peripheral edge of the noise-insulating wall contacts with an inner peripheral surface of the larger-diameter tubular portion, and when this displacement is canceled, the outer peripheral edge is engaged with an engagement portion on the larger-diameter tubular portion, so that the noise-insulating wall is reversed to be formed into a conical wall-shape in reverse to the initial shape, thereby forming a closed space between the noise-insulating wall and the shield wall.
