Abstract
An assistance apparatus includes a first and second wires coupling an upper-body belt and a left knee belt to each other on or above a front and back parts of a body of a user, respectively, a third and fourth wires coupling the upper-body belt and a right knee belt to each other on or above the front and back parts, respectively, a motor, a first sensor that detects at least tensions of the first and third wires, and a control circuit. The control circuit controls the motor to generate, when the first wire is broken, in the second wire, a tension less than a tension of the second wire during no break in the first wire, and to generate, when the third wire is broken, in the fourth wire, a tension less than a tension of the fourth wire during no break in the third wire.
