A pointer device for an indicator instrument, in particular for a vehicle; the device comprising: - a body, which is defined by a single piece, is made of a light-guiding material and comprises: a) a shaft having an axis and comprising a free surface for receiving light from a light source; b) a hub, which is coaxial with said shaft and has an external surface comprising a rear surface facing said shaft; c) a pointer, which projects radially outwards from said hub; - a shield, which covers said rear surface so as to block the light emitted, in use, by said rear surface; and - a cap, which is defined by at least one piece separate from said body and is mounted on said hub in a fixed position; the external surface of said hub further comprising: - an emitting surface; - a first reflecting surface configured to reflect and direct a first light flow from said shaft to said pointer; and - at least a second reflecting surface (41a, 41b), which is configured to reflect and direct a second light flow from said shaft to said emitting surface and comprises at least one area set apart from said first reflecting surface; said cap comprising an appendage and defining at least one light-permeable passageway aligned with said emitting surface, to let the second light flow pass to the outside; characterized in that - said hub comprises a portion, which radially delimits a recess open at an axial end of the hub and axially ends at said emitting surface so as to guide said second light flow to said emitting surface; - said appendage is arranged between said emitting surface and said first reflecting surface in such a manner to define a barrier that blocks the part of the light that leaves the hub via said first reflecting surface into said recess in order not to reach said emitting surface. - a body, which is defined by a single piece, is made of a light-guiding material and comprises: a) a shaft having an axis and comprising a free surface for receiving light from a light source; b) a hub, which is coaxial with said shaft and has an external surface comprising a rear surface facing said shaft; c) a pointer, which projects radially outwards from said hub; a) a shaft having an axis and comprising a free surface for receiving light from a light source; b) a hub, which is coaxial with said shaft and has an external surface comprising a rear surface facing said shaft; c) a pointer, which projects radially outwards from said hub; - a shield, which covers said rear surface so as to block the light emitted, in use, by said rear surface; and - a cap, which is defined by at least one piece separate from said body and is mounted on said hub in a fixed position; the external surface of said hub further comprising: - an emitting surface; - a first reflecting surface configured to reflect and direct a first light flow from said shaft to said pointer; and - at least a second reflecting surface (41a, 41b), which is configured to reflect and direct a second light flow from said shaft to said emitting surface and comprises at least one area set apart from said first reflecting surface; - an emitting surface; - a first reflecting surface configured to reflect and direct a first light flow from said shaft to said pointer; and - at least a second reflecting surface (41a, 41b), which is configured to reflect and direct a second light flow from said shaft to said emitting surface and comprises at least one area set apart from said first reflecting surface; - said hub comprises a portion, which radially delimits a recess open at an axial end of the hub and axially ends at said emitting surface so as to guide said second light flow to said emitting surface; - said appendage is arranged between said emitting surface and said first reflecting surface in such a manner to define a barrier that blocks the part of the light that leaves the hub via said first reflecting surface into said recess in order not to reach said emitting surface.
