CONSTITUTION: A load controller of a weight mechanism loads a weight to an exerciser by oscillating a weight by using a tensile wire. An automatic load controller comprises multiple weights(100); a binding part(120);a motor part(140); a control part; and a user setting part. A binding groove that penetrates through a body of the weight in a load direction is formed in each of the multiple weights. The binding part is inserted to the binding groove and is bound with the weights at the number of weights according to a depth of the insertion. The motor part is connected with the binding part and controls the insertion depth of the binding part according to a motor driving signal. The control part controls the motor part. The user setting part receives information related to load setting from outside and transmits the information to the control part. The control part generates the motor driving signal corresponding to the information related to the load setting as received from the user setting part, and transmits the motor driving signal to the motor part.
