摘要： 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.
