Abstract: PROBLEM TO BE SOLVED: To provide a grommet, improved in work efficiency of mounting while keeping high sealing performance.
SOLUTION: When a fastening band is fastened to the outer peripheral surface 11 of the grommet 10 after the grommet 10 is mounted on boots, the grommet 10 is reduced in diameter so that the stress is applied in the circumferential direction. Thus, shearing stress is applied to a connecting piece 14c provided in a gap in the vertical direction to the circumferential direction. Therefore, the connecting piece 14c is deformed or broken by the shearing stress. Circular-arc members 10A, 10B, 10C are slid relatively to each other to reduce the gap S in the circumferential direction or eliminate the gap S without deformation of the circular-arc members 10A, 10B, 10C themselves.
