ABSTRACT:
In a conventional grommet, that portion of a tapering, reduced-diameter portion, extending from an insertion hole of a minimum diameter to an insertion hole of a maximum diameter, is linearly varying. Therefore, when enlarging the diameter of the reduced-diameter portion, a large diameter-enlarging force is required, and the efficiency of the operation is low. A grommet 21 of the invention includes a mounting base portion 27 of a different-diameter tubular shape having a larger outer-diameter portion 23 at one end thereof and a smaller outer-diameter portion 25 at the other end thereof, and an annular groove 31 for fitting on a peripheral edge of a hole, formed through a panel of a vehicle, is formed in an outer peripheral surface of the larger outer-diameter portion 23, and the interior of the mounting base portion 27 defines a passage space 29 for a wire harness. A cylindrical portion 33 is formed on and extends continuously from the smaller outer-diameter portion 25 of the mounting base portion 27, and an inner periphery of the cylindrical portion corresponds to a wire harness having a maximum outer diameter. A truncated cone-shaped portion 37 is formed on and extends continuously from a distal end of the cylindrical portion 33, and the truncated cone-shaped portion has an open distal end corresponding to a wire harness having a minimum outer diameter.
