light 144 thus conducted by a reflector 145 in the interior of the rotational center 142 is emitted from the indicator body 141 as it is passing through the indicator body 141 specifically by the function of a hot stamp 146 provided on the lower surface a greater amount of light 148 is emitted from an upper surface 147 thereby improving the visibility of the indicator 140 specifically in this embodiment as shown in fig6 the indicator 140 is formed to have a rectangular cross section and side surfaces 149 and 150 of the indicator body 141 are perpendicular to a dial plate 130 thus lights 151 and 152 coming through the side surfaces 149 and 150 of the indicator body 141 advance in directions substantially parallel to the surface of the dial face 130 by virtue of the above configuration and function of this embodiment of the indicator 140 if light conducted in the longitudinal direction of the indicator body 141 comes through the side surfaces 149 and 150 of the indicator body 141 which are perpendicular to the surface of the dial plate 130 the light advances in the direction parallel to the dial face 120 and thus does not light the dial face 120 especially near the indicator 140 therefore occurrence of halation which deteriorates the visibility of the indicator and was a prior art problem is prevented thereby improving the visibility of the indicator the indicator of this embodiment is preferably used with the above described dial plates but can also be used with a dial plate as shown in fig8 which is of the same configuration as the prior art dial plate in which only one of the marking and the dial face is light transmissive through.
