Publication number: 20080230257Abstract: A grommet 1 has a central shaft 2 through which a wire harness 5 is inserted. A circular connection portion 31 is provided continuously to the periphery of the central shaft 2. A convex cross-sectionally V-shaped ring-like lip 32 is extensibly provided to the circular connection portion 31 in the direction of the center of the central shaft. A flange portion 33 is provided continuously to the lip portion 32. When the grommet 1 is assembled to a body panel 10, the lip 32 of the grommet 1 is extended in the direction of the center of the central shaft 2 of the grommet 1, thereby reducing the diameter of the lip 32. Then, the lip 32 is inserted into the through hole 12 of the body panel 10. Thus, a low insertion force is sufficient when the grommet is inserted thereinto. Consequently, the assemblability of the grommet 1 is enhanced.Type: ApplicationFiled: March 7, 2008Publication date: September 25, 2008Applicants: YAZAKI CORPORATION, HONDA MOTOR CO., LTD.Inventors: Nozomi KAWASAKI, Yasuyoshi SERIZAWA, Tatsuo SHIMADA, Tetsuya MITANI, Hiroyuki KUROKAWA

Patent number: 7172034Abstract: A boring control method for a machine tool for automatically boring a deep hole using a central control means performing boring with programmed control. In the boring, the number of processing and steps of the machine tool is kept minimum, load torque of a tool is detected continuously using torque detection means, and the movement of the tip portion of the tool desired for a piece of work is confirmed from a reference point to a hole bottom using a Z-axis movement device.

Patent number: 6709045Abstract: A roof side rail has a closed cross-section formed by integrating side rail outer and inner, and a part of the side rail forms an upper edge of a vehicle body side opening. A pipe-shaped reinforcing member is inserted into the side rail from the front side thereof to a part forming the upper edge of the opening, and is fixed to the side rail inner. Therefore, even when cross-sectional areas between the front side of the side rail and the part of the side rail forming the upper edge of the opening differ, both of which are connected to each other via a step part deviated to the largest degree, the stiffness of the step part is increased, and the number of parts and man-hours required for welding are reduced.Type: GrantFiled: October 10, 2002Date of Patent: March 23, 2004Assignee: Mitsubishi Jidosha Kogyo Kabushiki KaishaInventors: Hirotaka Shuto, Hiroyuki Kurokawa, Tatsuji Shimizu, Eisuke Okamoto
