Publication number: 20240123921Abstract: Objects are: to make a fixing structure in which an engagement part of a fixing member is inserted and fixed in a through hole of a plate-shaped member, into a structure in which the fixing member is easily detached from the through hole and is less likely to be damaged or broken when being detached; and to, in doing so, maintain the dustproof and waterproof performance, the molding processability, and the elasticity of a dish-like contact portion of the fixing member at the conventional level, and suppress a size increase. To attain these objects, in a fixing structure, arc-shaped bent portions are respectively formed at both ends of a dish-like contact portion which annularly contacts a through hole surrounding portion from a near side in an insertion direction, and are guide portions for a detachment jig to enter the inside of the dish-like contact portion in the fixing structure.Type: ApplicationFiled: October 10, 2023Publication date: April 18, 2024Inventors: Toshio IWAHARA, Katsuya HIRAKAWA, Makoto KATO, Toshinori MURAMOTO

Patent number: 11456581Abstract: In a vehicle body, a body portion having a base end side portion is engaged with a plate-shaped member and extending along the plate-shaped member toward the leading end side, and a removal-preventing portion for preventing the wire harness stored in a space between the plate-shaped member and the body portion from being removed from the leading end side of the body portion. The wire harness stored in the space is prevented from being removed at the leading end side of the body portion by the removal-preventing portion pivoting according to the storage. By a series of rotations of the removal-preventing portion up to the storage, a pivotal body upper portion of the removal-preventing portion disposed at a high position in a height direction extending from the plate-shaped member is moved to a lower position, thereby reducing the height of the entirety of the routing structure.Type: GrantFiled: July 6, 2021Date of Patent: September 27, 2022Assignee: DAIWA KASEI INDUSTRY CO., LTD.Inventors: Makoto Kato, Katsuya Hirakawa
