A gear device includes a gear means configured to transmit a torque of a motor to a rotating member. The gear means includes a rotor and an armature. The gear device further includes a coupling force applying part and a resistance force generating part. The coupling force applying part is configured to apply a coupling force so as to couple the rotor and the armature to each other. The resistance force generating part is configured to apply a resistance force acting against the coupling force to the gear means along with movement of the gear means away from the rotating member. |
