  • Patent number: 9302569
    Abstract: A waterproofing structure for a vehicle door having a cover member for closing a service hole formed in an inner panel, and a clip for detachably mounting the cover member to the inner panel. The cover member includes a seat portion and a tool hole. The seat portion is formed on an outer side of the cover member facing the inner panel, and the clip is mounted thereto. To detach the clip from the inner panel, a tool is inserted into the tool hole from an inner side. The clip includes a countersunk head covering the tool hole to seal the hole while the clip is mounted to the seat portion. The seat portion serves as a canopy with respect to the tool hole, and changes a course of water entering an interior of the door and falling toward the tool hole from the outer side of the cover member.

  • Patent number: 8567017
    Abstract: A two-member assembling structure in which a clip mounted to a pedestal of an attachment member is inserted into a clip hole of a mating member, the clip includes a pedestal coupling portion coupled to a rib of the pedestal, an engaging arm adapted to pass through the clip hole while undergoing elastic deformation when the clip is inserted into or removed of the clip hole, an engaging surface formed on an outer side surface of the engaging arm and capable of engaging with a hole edge of the clip hole, a stable portion extending from the engaging surface and opposed to the rib of the pedestal so as to be capable of contacting therewith, and a regulating portion protruding toward the rib of the pedestal from a position in the vicinity of the stable portion. As the pedestal of the attachment member, there are prepared at least three kinds of pedestals for low retention, medium retention, and high retention.

  • Publication number: 20110167590
    Abstract: For receiving and stopping movement of a movable member approaching to a fixed member in order to absorb impacts, a cushion clip includes a clip body capable of being mounted by inserting into a mounting hole formed in one of the fixed member and the movable member, and a cushion body capable of absorbing impacts by resilient deformation. The clip body made of rigid resin material and the cushion body made of soft resin material are integrally joined to each other at a mutual joint portion by a two-material molding process. At the mutual joint portion, the clip body includes a base portion entering into inside of the cushion body, and a concave-convex configuration, such as ribs, is provided to the base portion for increasing a contact area with the cushion body.
