<P>PROBLEM TO BE SOLVED: To prevent a grommet from being excessively inserted in a through- hole and also to prevent the grommet from being eccentric relative to the through-hole. <P>SOLUTION: A tapered receiving plane 21 is formed at the internal periphery of a socket 20 of the grommet 35 in the through-hole 19, and a tapered abutting plane 41 that abuts on the receiving plane 21 in a state that the grommet 35 is inserted in a normal insertion position is formed at the external periphery of the grommet 35. Since the abutting plane 41 abuts on the receiving plane 21 in the same direction as the direction of the insertion, the grommet 35 is prevented from excessively being inserted in the through-hole 19. Even if the grommet 35 receives an external force in the direction where the grommet is eccentric relative to the through-hole 19, the receiving plane 21 receives a pressing force in the diametral direction from the abutting plane 41 side, thus preventing the grommet 35 from being eccentric. <P>COPYRIGHT: (C)2003,JPO |
