Abstract
An operation device includes a motor capable of forward and reverse rotation, a transmission mechanism configured to convert forward and reverse rotation of the motor into linear ascending and descending motion and to provide tactile stimulation on an operation unit, and a controller configured to control switching of an energizing direction of the motor. The controller is configured to control acceleration such that an amount of ascending movement of the operation unit is increased by increasing driving power in a forward rotation direction of the motor, and to control deceleration such that the ascending movement of the operation unit decelerates by supplying driving power in a reverse rotation direction of the motor, in a predetermined time from when the operation unit starts the ascending movement via the transmission mechanism until a target displacement amount is reached.
