Abstract:
A water-proof grommet comprising:a plate-shaped head having a predetermined thickness, a front surface, and a flat back surface, a square grommet body extending from the back surface of the head in a thickness direction of the head, at least two latch pawls which are connected to outer surfaces of the grommet body at a substantially central portion of the grommet body in a longitudinal direction, wherein an insertion hole is provided in a substantially central portion of the head, and a central hole communicating with the insertion hole is provided in a substantially central portion of the grommet body interposed between the at least two latch pawls, wherein each of the latch pawls comprises a tip end portion having an inner edge opposed to the grommet body and an outer edge located outward relative to the inner edge, wherein an inclined surface is provided at the tip end portion of each of the latch pawls, and the inclined surface is inclined away from the head from the inner edge toward the outer edge of the tip end portion of each of the latch pawls, wherein the grommet body is adapted to expand radially as a screw is threaded into the central hole of the grommet body so as to expand the grommet body radially outward and cause the outer surfaces of the grommet body to apply an outward pushing force to the latch pawls and thereby cause the tip end portions of the latch pawls to be displaced radially outward and toward the head.
