A tuning method for the exciting current-transmission torque characteristic of a power transmission apparatus is provided. A yoke (), which supports an electromagnet (), is accommodated in a groove () and is apart from the groove by a first distance (L) and a second distance (L). The exciting current-transmission torque characteristic is tuned by varying the first distance while keeping the second distance fixed. When the first distance is varied, the variation of the magnetoresistance of a magnetic path is relatively small. Therefore, the exciting current-transmission torque characteristic is more accurately tuned.
