A neutral position returning mechanism includes an actuator (44), a spring member (31,32) including plural elastic extending portions having spiral shapes identical to each other, and a case (21) holding the spring member (31,32) as to apply a stress to the elastic extending portions. The elastic extending portions extend spirally in a predetermined direction on a predetermined surface from the actuator (44) as a center of each of the spiral shapes. The elastic extending portions extend from the actuator (44) by equal angular intervals about the actuator (44). The neutral position returning mechanism provides an input device having a low profile. |
