Abstract A grommet for preventing water from leaking through the hole of a panel having a hard portion 10 made of a hard material and fixedly fitted in the hole of a panel, and a soft portion 20 made of a soft material and including an electric cord insertion part 23 and a waterproofing part 24. The hard portion is composed of a plurality of split parts whose coupled faces are provided with guide bars 16 and guide holes 17 in which the bars are slidably fitted so that the split parts can be moved away from each other in an expansionary manner as they remain coupled to each other to allow for insertion of the cord.
