[Solution to Problem] A motor-driven screwdriver operation information indicator (50) is retrofittable to a motor-driven screwdriver (10) to indicate information related to an operation of the motor-driven screwdriver (10). An indicator housing (58) of the operation information indicator (50) is secured to a supporting and securing member (52) configured to be secured to an outer peripheral surface (18) of a screwdriver housing (12) of the motor-driven screwdriver (10), thereby holding the indicator housing (58) at a rear position of a rear end portion (14) of the motor-driven screwdriver (10). An indication control circuit (78) disposed in the indicator housing (58) is connected to at least one of a motor-driven screwdriver drive control circuit (22) and an external control circuit to receive a signal from the circuit connected thereto. The indication control circuit (78) transmits a signal related to an operation of the motor-driven screwdriver (10) on the basis of the received signal and indicates information related to the operation of the motor-driven screwdriver 10 on an operation information indicating part (68). |
