1. A grommet, comprising: a smaller diameter tubular section, an increasing diameter tubular section, and a larger diameter tubular section, said smaller diameter tubular section being connected through said increasing diameter tubular section to said larger diameter tubular section in an axial direction, said smaller and larger diameter tubular sections configured to pass a wire harness for a motor vehicle therethrough, said grommet configured to be inserted into a through-hole in a vehicle body panel and a latching recess of the large diameter tubular section is engaged with a peripheral edge of said through-hole in the vehicle body panel; wherein a U-shape folded portion is provided between said smaller diameter tubular section and said increasing diameter tubular section, said folded portion extending outward from said smaller diameter tubular section and turning in an axial direction; wherein a flap section is provided on an outer periphery of said smaller diameter tubular section so that said flap section spreads conically from said smaller diameter tubular section toward said increasing diameter tubular section; and wherein said folded portion is stretched flatly when said grommet is inserted into said through-hole, and when said vehicle body latching recess is engaged with said peripheral edge said folded portion returns to its original shape, and a distal end peripheral edge of said flap section contacts with the vehicle body panel at a passenger room side to define a sound absorbing closed space.
