Abstract: Male terminals are respectively provided in terminal attachment portions formed on a flange unit. Female terminals and grommets are provided for a harness. A seal lip portion to be fitted into each of the terminal attachment portions is formed on each of the grommets. In the cylindrical terminal attachment portions the male terminals are individually accommodated while being electrically insulated from each other. The terminal attachment portions are arranged alternately in two rows so that a line segment obtained by connecting the respective centers of openings of the terminal attachment portions is a polygonal line. The openings are arranged to form the Olympic symbol. At a fore-end of each of the terminal attachment portions, slits are provided. Owing to the slits, the opening is likely to be enlarged when the rubber grommet is inserted therethrough. As a result, the placement of the rubber grommet is facilitated.

Abstract: A male terminal is provided in a terminal hole formed in a flange unit. A female terminal and a grommet having a sealing portion to be fitted into the terminal hole are provided to a harness. A distance from an end of the sealing portion to a fore-end of the female terminal is set smaller than a distance from a fore-end of the male terminal to an opening of the terminal hole. With such setting, the grommet is retained in the terminal hole even if the female terminal is disconnected from the male terminal, thereby ensuring support of the female terminal. Moreover, a stopper is attached so as to cover the terminal hole to prevent the grommet from slipping out of the terminal hole.

Abstract: A fuel pump includes an outer partitioning wall formed with an intake port; an inner partitioning wall formed with a discharge port; and an impeller housed between the outer partitioning wall and the inner partitioning wall, wherein each of the outer partitioning wall and the inner partitioning wall is formed with a fuel flow path that communicates with the intake port and the discharge port in a portion opposing a blade body provided on a periphery of the impeller, and the intake port is provided with an eddy current prevention section that prevents inflowing fuel from forming an eddy current.

Abstract: Male terminals 83 are respectively provided in terminal attachment portions 82 formed on a flange unit 7. Female terminals 84 and grommets 85 are provided for a harness 17. A seal lip portion 86 to be fitted into each of the terminal attachment portions 82 is formed on each of the grommets 85. In the cylindrical terminal attachment portions 82, the male terminals 83 are individually accommodated while being electrically insulated from each other. The terminal attachment portions 82 are arranged alternately in two rows so that a line segment obtained by connecting the respective centers of openings of the terminal attachment portions is a polygonal line. The openings 87 are arranged to form the Olympic symbol. At a fore-end of each of the terminal attachment portions 82, slits 89 are provided. Owing to the slits 89, the opening 87 is likely to be enlarged when the rubber grommet 85 is inserted therethrough. As a result, the placement of the rubber grommet 85 is facilitated.
