Patent number: 8247694Abstract: A curved wall portion along which a wiring harness is bendably extended has a foreign-matter-escape side opening, at one wall continuing to a top opening of an upward guiding cylinder of a protector. A foreign-matter-escape side opening on the other wall of the cylinder proximate to the opening is opposed to the curved wall portion. A projection on the other wall in the guiding cylinder and below the side opening of the wall has an upwardly sloping surface continuing thereto. A projection in the guiding cylinder is above the side opening of the other wall, traversing the cylinder. The protector includes one separate protector member and the other separate protector member, the former having a projection extending toward the latter to cover a joining area thereof.Type: GrantFiled: March 12, 2009Date of Patent: August 21, 2012Assignees: Yazaki Corporation, Toyota Jidosha Kabushiki KaishaInventors: Tsukasa Sekino, Seiji Iwahara, Makoto Nagasaki, Akihito Kouketsu, Hiroyuki Wakamatsu, Ryuuya Ishimaru, Yoshihiko Nakahama
