<p>PURPOSE:To prevent excessive deformation of inserting unit in attaching by making distances between plural circular arc type grooves arranged annularly actuate as ribs by arranging the plural grooves annularly through bulkheads. CONSTITUTION:Plural circular arc grooves 6...6 are formed from the upper face of a non-inserting unit 3 to the lower face of an inserting unit 2 so as to surround a blind hole 1. And bulkheads 7...7 between the circular arc grooves 6...6 are made to actuate as ribs connecting the outer circumferential wall of a boss unit 8 and the inner circumferential wall of the inserting unit 2. Therefore, when pressing the boss unit 8 to attach to a grommet mounting hole 10, the bulkheads 7...7 are actuated as ribs to prevent excessive deformation of the inserting unit 2 in attaching, and attachment to the grommet mounting hole 10 can be simplified and sealing performance can be improved.</p> |
