There is provided an assistance apparatus in which when assistance provided to a user in walking is to be stopped, a motor (114) reduces a tension of a first wire (110a1) and a tension of a second wire (110a2), which couple an upper-body belt (111) and a left knee belt (112a) to each other on or above a front part and a back part of a body of the user, to less than a second threshold value during a first stop period in a gait phase of a left leg of the user, the first stop period being a period from a period included in a first period and including a timing at which the left leg shifts from a stance phase to a swing phase to a start period of a second period, and reduces a tension of a third wire (110a3) and a tension of a fourth wire (110a4), which couple the upper-body belt (111) and a right knee belt (112b) to each other on or above the front part and back part of the body of the user, to less than the second threshold value during a second stop period in a gait phase of a right leg of the user, the second stop period being a period from a period included in a third period and including a timing at which the right leg shifts from the stance phase to the swing phase to a start period of a fourth period.
