Abstract
A grommet includes a smaller diameter tubular section, an increasing diameter tubular section, and a larger diameter tubular section. The smaller diameter tubular section is connected through the increasing diameter tubular section to the larger diameter tubular section in an axial direction. A U-shape folded portion is provided on a connecting portion (a middle diameter tubular section) between the smaller diameter tubular section and the increasing diameter tubular section. A flap section that spreads conically toward the increasing diameter tubular section is provided on an outer periphery of the smaller diameter tubular section or an outer periphery of the folded portion. The folded portion is stretched straightly when the grommet is inserted into a through-hole. When a vehicle body latching recess is engaged with a peripheral edge around the through-hole, the folded portion returns to the original shape, and a distal end peripheral edge of the flap section contacts with a vehicle body panel at a passenger room side to define a sound absorbing closed space.
