Abstract
A water-proof grommet is provided which includes a plate-shaped head, a polygonal grommet body, and at least two latch pawls connected at lower ends to the grommet body and arranged on an outside surface of a substantially central portion of the grommet body. The head is substantially flat at a back surface thereof, and the latch pawls are provided at tip end portions with at least one inclined surface inclined outward and downward from the grommet body and at least one adjacent flat portion. The grommet body is adapted to expand radially as a screw is threaded therein, so as to cause an outer surface of the grommet body to deform the latch pawls radially outward and thereby cause at least one of the inclined surface and the adjacent flat portion of the latch pawls to press a member being mounted toward the back surface of the head.
