PROBLEM TO BE SOLVED: To provide a motor device and a robot device that have an excellent durability.SOLUTION: A motor device comprises: a rotor; a transmission part hooked to at least a part of a peripheral surface of the rotor; a drive part moving the transmission part by a constant distance while making between the rotor and the transmission part be in a rotational power transmission state, and acting a drive force in a first direction so as to return the transmission part to a predetermined position in a state that the rotational power transmission state is cancelled; a coupling mechanism that has a first part movable in the first direction by the drive force of the drive part and a second part connected with the first part via a connector and movable in a second direction different from the first direction, and that is connected to the transmission part and the drive part; and a reception part receiving a part of the drive force acting on the connector. |
