Patent ID: 7654220

Claim:
An indicator comprising: a fixing member having two connection terminals formed thereon; a permanent magnet fixed to the fixing member; a coil rotatably supported on the fixing member for generating a torque by interacting with a magnetic field of the permanent magnet; an indicator needle mounted to undergo rotation with the coil; a first spiral spring connected at one end thereof to one of the connection terminals of the fixing member and connected at another end thereof to one end of the coil for urging the indicator needle in a direction opposite to a direction of the torque generated by the interaction between the coil and the magnetic field of the permanent magnet; and a second spiral spring disposed on the same plane as the first spiral spring and connected at one end thereof to the other one of the connection terminals of the fixing member and connected at another end thereof to another end of the coil for urging the indicator needle in the direction opposite to the direction of the torque generated by the interaction between the coil and the magnetic field of the permanent magnet, the first spiral spring being larger than the second spiral spring and being arranged on an outer peripheral side of and coaxially with the second spiral spring.
