Abstract
A drive unit for calibrating an indicator/meter of a vehicle is provided in which a pointer in an indicator for a vehicle can point immediately after an ignition switch is turned ON, and the frequency of seeing motion of the pointer in an initializing operation by a car driver is reduced. A sensing mechanism ( - ) is provided to sense an open/close operation of a door. Correspondingly to the sensing of the sensing mechanism ( - ), a drive-start mechanism ( - ) starts rotation of a stepping motor using a drive mechanism ( - ) for initialization. The drive mechanism ( - ) during initialization rotates the stepping motor to move a driven member toward a stopper.
