<p><P>PROBLEM TO BE SOLVED: To provide a grommet which has a simple configuration and can be easily detached from both sides of a panel. <P>SOLUTION: The grommet 1 is made of an elastic material and allows a wire harness 4 to be inserted through the inside. The grommet 1 includes a small diameter cylindrical portion 10, a large diameter cylindrical portion 20, a coupling cylindrical portion 30 and a locking portion 40. The coupling cylindrical portion 30 couples the small diameter cylindrical portion 10 to the large diameter cylindrical portion 20, and is provided so as to be freely elastically deformed between a state in which the small diameter cylindrical portion 10 is positioned outside the large diameter cylindrical portion 20 and a state in which the small diameter cylindrical portion 10 is positioned inside the large diameter cylindrical portion 20. When the small diameter cylindrical portion 10 is positioned inside the large diameter cylindrical portion 20, the locking portion 40 locks the small diameter cylindrical portion 10 to the inside of the large diameter cylindrical portion 20, and locks the large diameter cylindrical portion 20 to the inside of a hole 3 of the panel 2. The locking portion 40 includes a protrusion 25 protruding from the large diameter cylindrical portion 20 toward the small diameter cylindrical portion 10, and a recess provided on the small diameter cylindrical portion 10 and engaged to the protrusion 25 with an external wall 31 of the elastically deformed coupling cylindrical portion 30 sandwiched between itself and the protrusion 25. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
