  • Publication number: 20220326515
    Abstract: In a vehicle display device, a locking mechanism has a first support part that supports a first end of a display panel and a second support part located at a position relatively different from the first support part. The second support part has a pair of urging portions that urge the display panel in a support state, and a first receiving portion that receives a lower surface of a second end of the display panel. Each of the urging portions is formed curving in an S shape when viewed from the optical axis direction, and a distal end portion formed at an end opposite to the fixed end portion has a second receiving portion that protrudes from an abutting surface toward the display panel and interposes the second end of the display panel between the second receiving portion and the first receiving portion, in the support state.

  • Patent number: 9248779
    Abstract: A mounting structure including: an outer housing having a first locking portion; a ceiling including a lamp opening portion in a central portion thereof; an inner housing including: a first locking facing portion which is locked in the first locking portion of the outer housing; and a second locking portion on and directly attached to the inner housing; and a reinforcement having a second locking facing portion which is locked on the second locking portion of the inner housing. The ceiling is fixed between the outer housing and the inner housing by locking the first locking facing portion of the inner housing in the first locking portion of the outer housing via the lamp opening portion in the ceiling. A bracket portion shaped so as to follow a shape of an upper side of the ceiling is provided along an outer circumference of the inner housing.

  • Patent number: 7562857
    Abstract: A design part composing a lamp unit includes a plate part positioned at a cabin side and covering an attaching hole of a roof trim, and a pair of vertically extending parts. The vertically extending part includes a frame part vertically extending from the plate part in a direction perpendicular to the plate part, and a movable piece continued to a connecting part of the frame part at a far side from the plate part. When a function part is pushed into between the pair of movable pieces, the gap between the movable pieces is increased, and a locking margin between the movable piece and an outer edge of an attaching hole is increased. Thus, holding force to hold the roof trim is secured.
