摘要： A pointer device for an indicator instrument, in particular for a vehicle, is provided with a light-guide body defined by a single piece, which, in use, receives light from a light source and has a hub and a pointer radially protruding from the hub; the hub has a surface covered by a shield and a light transmission portion, which, on the opposite side, ends with at least one light emission area; the device is provided with a cap defined by a single piece, which is separate from said light-guide body and has an intermediate portion and a lateral portion arranged in an inner and outer radial position, respectively, relative to the light transmission portion; the cap has at least one through opening aligned with the light emission area and connection portions extending radially and joining the intermediate portion to the lateral portion.

摘要： 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.
