Abstract
Official abstract text for this publication.
A vehicle instrument device includes a housing for attaching a dial plate, a light guide plate housing recess formed in the housing, a light guide plate that is housed in the light guide plate housing recess, and guides illumination light to the dial plate, a claw that fixes the light guide plate to the housing, and a press-fitting rib that is provided in a side surface of the light guide plate, and extends toward a side wall of the light guide plate housing recess. The press-fitting rib includes a tapered portion for increasing a height from a back side to a front side of the light guide plate housing recess and a tapered portion for decreasing a width from the back side to the front side of the light guide plate housing recess.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle instrument device comprising: a housing for attaching a dial plate; a light guide plate housing recess formed in the housing; a light guide plate that is housed in the light guide plate housing recess, and guides illumination light to the dial plate; a claw that fixes the light guide plate to the housing; and a press-fitting rib that is provided in a side surface of the light guide plate, and extends toward a side wall of the light guide plate housing recess, wherein the press-fitting rib includes a tapered portion for increasing a height from a back side to a front side of the light guide plate housing recess and a tapered portion for decreasing a width from the back side to the front side of the light guide plate housing recess. 2. The vehicle instrument device according to claim 1 , wherein a tapered angle of the tapered portion for increasing a height is set to be equal to a tapered angle of the tapered portion for decreasing a width. 3. The vehicle instrument device according to claim 1 , wherein areas of portions of the press-fitting rib which are wedged into a side wall of the light guide plate housing recess are the same in each portion in a depth direction.
