ABSTRACT:
A force feedback input device includes an operation member having a shaft and operated by an operator, detection means, such as a rotary encoder, for detecting an operating status of the operation member, an actuator for providing force feedback to the operation member, control means for controlling the actuator based on a detection signal output from the detection means, and stopper means for restricting displacement of the operation member in a predetermined operational direction. The stopper means includes a ratchet mechanism to disengage ratchets from corresponding gear teeth in response to the detection signal from the detection means.
