  • Patent number: 10584985
    Abstract: A pointer device has a light-guiding body, including a shaft, a hub coaxial with the shaft and having a rear surface covered by a shield, and a pointer, which projects radially from the hub. A cap is defined by at least one piece separate from the light-guiding body and is mounted on the hub in a fixed position. The hub has an emitting surface, a first reflecting surface configured to reflect and direct a first light flow from the shaft to the pointer, and at least a second reflecting surface, which is configured to reflect and direct a second light flow from the shaft to the emitting surface and is, at least in part, set apart from the first reflecting surface. The cap has at least one light-permeable area, aligned with the emitting surface, and a barrier arranged radially between the emitting surface and the first reflecting surface.
