Abstract
There is provided an indicator in which a moving member 9 on which a pointer 21 is installed is caused to run on a guide rail 1 formed along a scale formed on a dial, characterized in that the moving member 9 comprises a first support member 11 for pivotally supporting a plurality of pulleys 17 which are arranged along the guide rail 1 and a second support member 13 for pivotally supporting at least a pulley 17, and in that the plurality of pulleys 17 pivotally supported on the first support member 11 and the pulley 17 pivotally supported on the second support member 13 hold the guide rail 1 therebetween and the first support member 11 and the second support member 13 are assembled to each other so as to slide in an inter-axis direction of the plurality of pulleys 17 which are pivotally supported on the first support member 11 and the pulley 17 which is pivotally supported on the second support member 13, the indicator having further a spring member 15 for biasing the first support member 11 and the second support member 13 in a direction to reduce an inter-axis space therebetween.
