PURPOSE: A whole radiative type pointer structure reduces the number of parts assembled to increase productivity and reduce manufacturing cost. CONSTITUTION: The pointer structure comprises a pointer supporter(8), a pointer(9) and a cap(2). The pointer supporter(8) comprises a disk part(81), a hub(82), a protrusive part(83), a light refracting groove(84) and assembling holes(85). The hub(82) is protrusive on the center of the bottom surface of the disk part(81). The protrusive part(83) is extended long from the disk part(81) to the back side thereof. The light refracting groove(84) is formed in front of the protrusive part(83). The assembling holes(85) are formed perpendicularly on both sides of the disk part(81). The pointer(9) is inserted to the top part of the pointer supporter(8) and comprises a disk part(91), a pointer arm(92), a balancing part(93), assembling holes(94) and multiple light receiving holes(95). The pointer arm(92) is extend long from the disk part(91) to the front side thereof. The balancing part(93) is extended short to the rear side. The assembling holes(94) are formed perpendicularly on both sides of the pointer(9). The cap(2) covers the disk part(91) of the point(9) and the balancing part(93). The light generated by a light source is transmitted through a light guiding body to the pointer supporter(8), is transmitted to the pointer(9) upward by the light refracting groove(84), is transmitted to the pointer arm(92) through the light receiving holes(95)) and is diffused.
