  • Patent number: 10758060
    Abstract: A cover-material fastening clip includes a locking portion having a guide piece and a hook which includes an extension portion and a distal end portion. The guide piece extends includes a bent portion bent and extended toward the distal end portion. An insertion opening having a predetermined gap and allowing a wire to be inserted therethrough is positioned between the bent portion and the distal end portion. A distal end portion of the guide piece extending from the bent portion is an elastic piece portion being elastically deformed to be spaced from the distal end portion and to widen the insertion opening. In a part of the locking portion, which is located within a range, in which the elastic piece portion can be elastically deformed and thus moved, an escape space is provided to allow a distal end of the elastic piece portion to be positioned therein.

  • Patent number: 8662807
    Abstract: In case when an external force in a direction of pulling out from a female member acts on a male member in a fully fastened state, the male member moves in an axial direction, and a position where claw parts of engaging leg pieces engage moves from mounting parts and to contact parts. An engaging slot is formed on the contact part, and the engaging slot therefore engages with the claw part of the engaging leg piece. Movement in the direction of rotation of the male member is thereby restricted, and the male member is moved in state along the axial direction, so that the claw parts of the engaging leg pieces do not engage with engaging holes, and a state in which a vehicle body panel and a trim board are sandwiched by a flange part and the engaging leg pieces can be maintained.

  • Publication number: 20120087762
    Abstract: To obtain a fastener, and a structure for fastening a member to be fastened, with which a sufficiently locked state can be maintained even when the male member is pushed from the back. In the case when an external force in a direction of pulling out from a female member (14) acts on a male member (16) in a fully fastened state, the male member (16) moves in an axial direction, and a position where claw parts (34) of engaging leg pieces (28) engage moves from mounting parts (58) and (60) to contact parts (54) and (56). An engaging slot (62) is formed on the contact part (56), and the engaging slot (62) therefore engages with the claw part (34) of the engaging leg piece (28).

  • Patent number: 7705871
    Abstract: An image forming apparatus includes an optical writing device. The optical writing device includes an optical writing unit that emits laser light beams toward image carriers, an outer case that accommodates the optical writing unit, and air supplying devices that supply air into the outer case. The outer case includes openings through which the laser light beams pass. Another image forming apparatus includes an optical writing device that emits laser light beams toward image carriers to form latent images thereon, partition members that are interposed between the image carriers and the optical writing device and that have openings elongating along a scanning direction of the optical writing device, and shutter mechanisms including shutter members to open and close the openings. The laser light beams are emitted from the optical writing device toward the image carriers through the openings.
