Latest Patents

One of Tatsuo Shimada's key patents is for a grommet and the assembling method therefor. This grommet features a central shaft through which a wire harness is inserted. A circular connection portion is continuously provided to the periphery of the central shaft. Additionally, a convex cross-sectionally V-shaped ring-like lip is extensibly provided to the circular connection portion in the direction of the center of the central shaft. A flange portion is also continuously provided to the lip portion. When the grommet is assembled to a body panel, the lip of the grommet is extended towards the center of the central shaft, reducing the diameter of the lip. This design allows for a low insertion force when the grommet is inserted into the through hole of the body panel, thereby enhancing the assemblability of the grommet.
