Abstract: A tightening device includes a mobile part, a bolt tensioner, a bolt tensioner operation part, a positioning part, and a controller. The mobile part can be moved by driving control. The bolt tensioner performs a tightening operation for a bolt by operation of the operation part. The positioning part is mounted on the mobile part and is mounted with the bolt tensioner and the operation part, and positions a three-dimensional position of the bolt tensioner. The controller causes the mobile part to move so that a distance to the bolt falls within a certain value, causes the positioning part to operate so that the three-dimensional position becomes a position where the bolt is tightened after the mobile part is moved, and drives the operation part so that the bolt tensioner performs the tightening operation after the three-dimensional position is determined to be the position where the bolt is tightened.
