An attachment structure for installing a lighting device on an attachment target, includes a hole formed in a bottom surface of the attachment structure for letting light from the lighting device pass through the hole, and a plurality of ribs formed around the hole. The plurality of ribs are substantially flush with each other in a lighting device placement area configured to receive a bottom surface of the lighting device, so that the lighting device is positioned with respect to the bottom surface of the attachment structure in a height direction of the lighting device.

Attachment structure of lighting device

A light-emitting device includes a board, a light-emitting element mounted on a surface of the board, a support member on which the board is placed, and a cover having a plate shaped main cover body covering the light-emitting element and a tubular portion which receives a light guide body that guides light emitted from the light-emitting element. The main cover body includes a base, a protrusion protruding from the base toward the board, and a ridge disposed on a protruded end of the protrusion. A step is formed by the protrusion and the ridge, and the protrusion and the ridge extend in a same direction along the base.

Light-emitting device

A light guide body is held in a more compact holder. In a lighting device (A) including a light emitter (), an optical fiber (), and a holder () configured to hold the optical fiber () with the optical fiber () facing the light emitter (), the holder () includes two sandwiching portions () configured to engage with each other in a state in which a holding target portion () of the optical fiber () held by the holder () is sandwiched in a first direction crossing an extending direction of the holding target portion (). Two sandwiching portions () engage with each other at positions adjacent to the holding target portion () in a second direction crossing both of the extending direction and the first direction.

Lighting device

An attachment structure of a lighting device has: a holder provided on a top surface of a door pocket that constitutes a door lining, the lighting device being placed in the holder; walls for fixing the lighting device placed in the holder; a light source supporting part; and a connector supporting part. In this case, the attachment structure and the top surface of the door pocket are configured integrally.

A light-emitting device includes a board holding an end of a connection terminal and on which an electronic component is mounted, a light-emitting element mounted on a surface of the board, a support member on which the board is placed, and a cover mounted in the support member. The cover includes a main cover body that is of a plate shape and covers the light-emitting element, and first engaging portions that are convex and formed on the main cover body. A light guide passes therethrough light emitted from the light-emitting element and is disposed on the main cover body. The support member includes a chamber that is defined therein and accommodates the board and the main cover body, second engaging portions that are formed therein and engage with the first engaging portions, and the first engaging portions are provided near the light guide.

A light-emitting device comprises: a substrate that holds one end of connection terminals and on which is mounted an electronic component; a light-emitting element that is mounted on one face of the substrate; a support member on which the substrate is mounted; and a cover section that positionally locates and holds the substrate, by mounting on the support member in a condition abutting one face of the substrate. The cover section has a cover section body that covers one face of the substrate; on the cover section body, a light guide is provided, through which passes the light that is emitted from the light emitting element, in a condition in which movement thereof is restricted along directions on either side of the substrate.

A backrest of a seat includes: a pad including a slit air guide hole which penetrates the pad from a front surface of the pad to a rear surface of the pad; a base member for blocking the air guide hole on a rear side of the pad, the base member including an inlet hole communicated with the air guide hole; and a cover for blocking the air guide hole on the front surface of the pad, the cover including a plurality of outlet holes communicated with the air guide hole.
