<p>A housing of a rotary sensor houses a detection unit, and is attached to the body of a motorcycle. A rotor formed from a conductive material is provided so as allow free rotation relative to the housing and rotates together with a stand when this rotates. A detected unit is configured with a portion of said rotor. A detection unit has a circuit substrate on which a coil comprising a planar coil is formed. The coil is driven at a high frequency by an integrated circuit mounted on the circuit substrate, and the conductance of the coil varies with the change in the distance thereof from the detected unit accompanying rotation of the rotor. The integrated circuit detects whether the stand is in an upright position or in a storage position from the change of the coil conductance.</p> |
