Is located around the case member 50 in a state adjacent to the case member 50, the operation portion 81 is positioned immediately above the position, and the switch element 82 is positioned directly below the position.

  Therefore, when the operation unit 80 in a state in which the connecting portion 90 is in the space S as in the present embodiment is disposed corresponding to the opening 62 c of the invisible portion 62, the portion in which the connecting portion 90 is in the space S Since the formation area of the invisible portion 62 is smaller than in the past, it is possible to provide a vehicular instrument D1 capable of realizing miniaturization.

  As described above, in the present embodiment, the light guide member 40 is provided with the light guide main body 41 provided corresponding to the information display body 10, and the first and second light illumination members from the respective light sources 30 can be introduced. In the space S formed between the first light introducing portion 42 and the second light introducing portion 43, the leg portion 52 (case member 50) is integrally formed. Since the area where the invisible portion 62 is formed is smaller than in the prior art by the amount by which the connecting portion 90 sinks into the empty space S by arranging the connecting portion 90 as a functional component provided in the embodiment, miniaturization can be realized Vehicle meter D1 can be provided. In addition, the operation unit 81 and the information display body 10 to be operated by the operation unit 81 can be disposed in a close proximity to each other, and the relationship between the operation unit 81 and the information display body 10 can be enhanced. .

  Moreover, although this embodiment demonstrated the example which arrange | positioned the connection part 90 as a functional component integrally provided in the leg part 52 (case member 50) to the vacant space S, for example, to the leg part 52 (case member 50) It is good also as composition arranged as a part of empty space S as connecting part 90 as a functional part provided integrally. In short, according to the present invention, it is sufficient that the connecting portion 90 as a functional component integrally provided in the case member 50 be disposed in at least a part of the space S. It is possible to reduce the formation area of the invisible portion 62 by the area of the connection portion 90 positioned to be embedded, and there is an advantage that miniaturization can be realized.
