Abstract
A tool device has a deceleration unit, a tip tool, and a reaction bar. The deceleration unit increases a torque that is input to the deceleration unit. The tip tool is rotated when receiving a motive force from the deceleration unit. The reaction bar is fixed to the deceleration unit. An external force can be made to act on the reaction bar to receive a reaction force that is generated during rotation of the tip tool.
