Abstract
Provided is a tightening device capable of capturing a change in a contact state of a member to be tightened, such as a bolt or the like, and also performing fastening. The tightening device tightens a bolt to a work piece in a state where a main body is engaged with the bolt, and includes: a magnet that holds the bolt with respect to the main body; and at least one lower cam member that enables fixation in a fixed state where a binding force on the bolt is larger than a holding force of holding the bolt by the magnet. The at least one lower cam member is capable of maintaining the fixed state before a tightening work of tightening the bolt to the work piece is performed and releasing the fixed state after the tightening work is started.
