Abstract: PURPOSE: A pointer for a vehicle is provided to prevent the pointer from leaking light by receiving less light and to prevent the pointer from smudging on a side portion of the pointer when light is transmitted from a plate to the pointer. CONSTITUTION: A preventing protrusion for leaking light is formed around a through hole of a plate(12). A rotating shaft(14a) of a pointer cap(14) penetrates the through hole of the plate. A diameter(D2) of an assembling hole of a light conductor(23) is minimized to rotate the rotating shaft. A thickness of the plate is reduced to insert a floor surface of the plate into the pointer cap. A sectional area of the plate is reduced not to form a corner portion in connecting to a pointer(10). Opacity is spread a floor surface of a weight(13). The weight is connected to an upper surface of the plate by the pointer cap. Thereby, less light of a bulb is received to the pointer in night traveling. Leaking light around the pointer is prevented by minimizing received light of the bulb around the pointer cap. A smudging on a side portion of the pointer is prevented when received light of the bulb is transmitted from the plate to the pointer.
