<P>PROBLEM TO BE SOLVED: To provide an input device which can improve an operational feeling by reducing an influence of a torque variation in a DC motor imparting a force sense without using a complex correction control and the like in a force feedback. <P>SOLUTION: The input device 3 has a shaft bearing 129 bearing a control knob 122 so as to be operable to be inclined. Two DC motors 190 and 191 engaged with a semicircular gear 136 are provided as a drive part for causing the torque of the force feedback to the control knob. In the two of the DC motors, pole axes connecting an S pole and an N pole of a stator are arranged to intersect at 30 degrees with each other. As a result, torque ripples of the DC motors cancel each other and the torque variation is smoothened. <P>COPYRIGHT: (C)2012,JPO&INPIT |
