Abstract

PURPOSE: To provide an instrument for impacting or striking nails or the like, comprising plunger moved downward through the attracting force of solenoid coil when current is passed through the coil, in which there are provided two solenoid coils, and resistance of one of these coils selected larger than that of the other coil, so that impact force can be held constant independently of power source connecting resistance.
