  • Publication number: 20240123921
    Abstract: 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.

  • Patent number: 9630573
    Abstract: Embodiments of the present invention may include a clip mounting seat having a clip attachment surface, a peripheral wall and an opening. The peripheral wall extends from the clip attachment surface. The opening opens a part of an outer peripheral edge of the clip attachment surface. The clip attachment surface has an attachment hole, a guide groove and a tongue. The guide groove guides an insertion of a neck portion of the clip from the opening into the attachment hole. The tongue protrudes from an edge of the guide groove towards the attachment hole. The tongue is deflected to permit the neck portion to enter from the opening into the attachment hole. When the neck portion moves from the attachment hole toward the opening, the tongue is deflected by the neck portion in a closing direction.

  • Patent number: 9630572
    Abstract: A clip may have a clip body configured to be attached to a rib formed in an attaching article and configured to be inserted into an attaching hole formed in an object panel. The clip body includes a clamping portion configured to be coupled to the rib via an engagement slot formed in the rib, and an engagement portion elastically engageable with the attaching hole. The engagement portion has a biasing body that is configured to elastically contact an outer surface of the rib when the engagement portion is deformed inwardly caused by an extraction load applied to the clip body. The biasing body is positioned so as to contact the outer surface of the rib in a position closer to a distal end of the rib than the engagement slot.
