Abstract
Abstract A steering sensor is installed in a vehicle by utilizing a clearance between a steering wheel and a turn signal switch assembly. This makes it possible to provide a steering sensor having a high degree of universality, since the sensor can be simply retrofitted on an existing vehicle not already having such a sensor. The steering sensor can be utilized widely in navigation or other systems requiring such a sensor.
