ABSTRACT:
An indicating gauge for automobiles for displaying the amount of a measurement on a gauge board by a movement. The movement comprises a pair of coils for generating a combined magnetic field in response to a predetermined measurement amount, a magnet rotor having a rotation shaft rotating dependent on the generated magnetic field, a counter shaft rotatably disposed in parallel to the rotating shaft, a pointer mounted on the tip of the counter shaft, a rotation gear secured to the rotation shaft and a counter gear secured to the counter shaft. To fix the pointer to 0 position of the gauge board, a stopper is provided in the counter gear. This obviates the another stopper on the gauge board. The number of parts is reduced, and assembling the gauge can be done easily.
