A force feedback input device including a decelerating gear mechanism that transfers the rotation of a motor held by a motor supporting body to an operation ring is provided. The force feedback input device includes a decelerating gear mechanism composed of a center gear attached to a rotating shaft of the motor. The shaft of a plurality of relay gears is rotatably supported by a gear holder (a upper holder and a lower holder) fixed to the motor supporting body so as to be engaged with the center gear. A rotatable internal gear having gears engaging with the relay gears at the inner circumferential surface, and the cylindrical rotating part of the operation ring is engaged with the outer circumferential surface of the internal gear so as to make the operation ring and the internal gear rotate integrally.
