  • Publication number: 20170355302
    Abstract: A manufacturing method of a display apparatus including a light blocking housing having a peripheral wall and formed at an inner side of the peripheral wall with a concave part, a light source arranged in the concave part, and a lid having an opposite surface to the housing, sealing the light source in the concave part, and having a light transmitting decorative surface formed at a part of the opposite surface except for an end portion, the manufacturing method includes: forming a top surface of the peripheral wall as a stepwise surface including an outer bonding surface and an inner stepped surface lowered more than the bonding surface by one step; and bonding the end portion of the opposite surface to the bonding surface in a state in which an end portion of the decorative surface is allowed to face the stepped surface.

  • Patent number: 9638389
    Abstract: A vehicle lighting device includes a case, a lens, a light guide, a waterproof member, hooks, and catches. The catches are elastically deformed outward to separate from an accommodation portion so that the hooks enter the catches from the side closer to the accommodation portion. Engaging surfaces of the hooks engage with catch surfaces of the catches so that the case and the lens are joined. The joining causes the waterproof member to be compressed. The engaging surfaces and the catch surfaces are inclined by an equal angle relative to an imaginary plane perpendicular to the arrangement direction of the case and the lens such that the catch surfaces are located inward of the engaging surfaces and close to the accommodation portion.

  • Patent number: 9557464
    Abstract: A lighting device for a vehicle includes: a transparent rod shaped light guide member having an incident surface of lights in an end face; a light source which is arranged so as to be opposed to the incident surface of the rod shaped light guide member and generates heat at a temperature or higher than a softening point of the rod shaped light guide member, lights emitted from the light source being allowed to be incident on the rod shaped light guide member from the incident surface so that the rod shaped light guide member emits lights in a linear form; and a transparent heat insulating part arranged between the light source and the incident surface of the rod shaped light guide member.
