Finger tool

Abstract

A finger tool (10) which tightens a fastening member has a housing (11), a force detector (12), a rotary body (15), and a rotation driving mechanism (13). The force detector (12) is arranged on the housing (11) such that, when the housing (11) is attached to a finger (1) of a person's hand, the force detector (12) contacts a finger underside (2) of the finger (1). The rotary body (15) is arranged such that at least a tip thereof is present outside the housing (11), and has a rotation axis parallel to a specified direction. The rotation driving mechanism (13) is housed in the housing (11) and rotates the rotary body (15) around the rotation axis thereof in the state the housing (11) is attached to the finger (1), in response to detection of a force having a component in the specified direction by the force detector (12).
