ABSTRACT:
In the traction apparatus, a control circuit has the following traction control process portions. First, a first traction control process portion winds up the slack portion of a wire by a motor to eliminate the slack of the wire connected to a body to be pulled. Next, a second traction control process portion converts a set traction force that is set by an operation portion to a traction amount to calculate a converted value and, by defining a predetermined amount of a traction amount set based on the converted value as an initial target value, continuously winds up the wire by the motor to that target value. Next, a third traction control process portion detects the traction force that is being applied to the body to be pulled by a load cell, calculates a drive stop time of the motor by defining the set traction force as a final target value on the basis of a detected output of the load cell and drives the drive mechanism, and stops the driving of the motor at a point of reaching the drive stop time.
