Disclosed is a traction apparatus that applies a desired traction force to a body to be pulled, the traction apparatus including: an operation portion that sets a traction force to be applied to the body to be pulled a traction mechanism that includes a fixture that fixes a wire to the body to be pulled, the wire that is connected to the fixture and a winding drum for the wire, and applies the traction force to the body to be pulled a driving means for winding up the wire by a traction source a traction force sensor that detects a traction force acting on the wire a control means for fetching a set output of a traction force that is set by the operation portion and a detected output of the traction force sensor and that controls driving of the driving means a first pulley that is rotatably held and that detects a load of the wire a coupling plate that is not directly fixed to a main body side of the traction apparatus a plate-shaped load sensor plate of which one end holds the coupling plate and of which the other end is fixed to the main body side of the traction apparatus and a load cell that is mounted on a surface of the load sensor plate wherein the control means performs a first traction control process of winding up a slack portion of the wire by the driving means to eliminate slack in the wire connected to the body to be pulled, a second traction control process of converting the traction force set by the operation portion to a traction amount and, by defining the predetermined amount of the traction amount set based on the converted value as a target value, winding up the wire continuously by the driving means to the target value, and a third traction control process of detecting the traction force that is applied to the body to be pulled by the traction force sensor to calculate a drive stop time of the driving means by defining the traction amount set by the operation portion as a final target value based on a detected output of the traction force sensor
