Abstract: A knee airbag device including an airbag cushion, a storage case in which is formed a horizontally long opening part where the expanded and deployed airbag cushion pops outs, a first flap for covering the airbag cushion exposed through the opening part such that the airbag cushion is retained in the storage case, and having a first weak part that breaks when pressed by the airbag cushion during expansion and deployment and a second flap, which is a component with a larger dimension in a length direction than the first flap and for covering an outer surface of the first flap so as to transverse in a short direction of the opening part a center part of the airbag cushion in a lateral direction, the second flap having a second weak part that breaks when pressed by the airbag cushion after rupture of the first weak part.

Abstract: An electric motor-driven screwdriver includes a control circuit having a memory stored with setting data and a computing unit controlling the electric motor-driven screwdriver based on the setting data. The computing unit sets an execution order of work processes based on a pre-designated piece of order setting data, and sets, based on a next operation setting value, a next operation to be performed after completion of the final work process. The next operation setting value is selectable from among a setting value for stopping the operation of the electric motor-driven screwdriver, a setting value for repeating a series of work processes, and a setting value for shifting to a series of work processes in an execution order determined based on another piece of order setting data.

Abstract: An electric motor-driven tool is configured to make a notification to a worker about a set value of tightening torque as necessary before starting tightening work. An electric motor-driven screwdriver includes an electric motor-driven screwdriver body capable of changing a setting of the magnitude of tightening torque to be applied when tightening a screw, and a notification device for making a notification to a worker about a set value of tightening torque. If the set value of tightening torque has been set to a value greater than a threshold value (reference value), a control circuit of the electric motor-driven screwdriver sends a notification execution signal to the notification device before the electric motor-driven screwdriver body is started to be driven, thereby enabling a notification to the worker to be made by the notification device.
