Abstract
An assistance apparatus includes first to eighth wires that couple an upper body belt to be worn on an upper body of a user to a first knee belt and a second knee belt to be worn above a left knee and a right knee of the user, respectively, and a motor. In a case of assisting the user in turning left, the motor generates, when a right leg of the user is in a stance phase, a tension larger than or equal to a first threshold in each of the second, fourth, sixth, and eighth wires at an identical timing. In a case of assisting the user in turning right, the motor generates, when a left leg of the user is in a stance phase, a tension larger than or equal to the first threshold in each of the first, third, fifth, and seventh wires at an identical timing.
