Abstract
An assistance apparatus includes a first wire and a second wire that couple an upper-body belt and a left knee belt to each other, respectively, a third wire and a fourth wire that couple the upper-body belt and a right knee belt to each other, respectively, and a motor. When assistance is stopped, the motor is configured to reduce tension of the first wire during a first stop period starting in a boundary period in a first period and ending in a start period of a second period, generate no tension in the second wire during the second period, reduce tension of the third wire during a second stop period starting in a boundary period in a third period and ending in a start period of a fourth period, and generate no tension in the fourth wire during the fourth period.
