Abstract
It is an object of the present invention to provide a reaction force generating apparatus which can be improved in size and weight. In the reaction force generating apparatus () having: an arm () which is rotated by a load, and an electric motor () for applying a reaction force to the arm (), the reaction force generating apparatus () further has: a support shaft () which is rotatably installed in a transmission passage () through which a reaction force is transmitted to the arm (); a gear () which is rotatably attached to the support shaft (); a sector gear () which is disposed on a downstream side of the transmission passage () from the gear (), and coupled to the gear (); an output shaft () which is rotatably installed in the transmission passage (), and to which the sector gear () and the arm () are attached; and a one-way clutch () which is interposed between the support shaft () and the gear () in the transmission passage (), wherein the one-way clutch () has: an engaged state in which, when the gear () is rotated in a first direction, the one-way clutch () connects the transmission passage () to the arm (); and a released state in which, when the gear () is rotated in a second direction, the one-way clutch () blocks the transmission passage (), and the sector gear () has a meshing portion (B) formed within a specific angular range in a rotation direction.
