Device for converting the rotary motion of an eccentric driven by a motor shaft into an oscillating motion of a working tool in electrically powered appliances, consisting of a double-armed rocker arm and an oscillating body, connecting the rocker arm with the eccentric, composed of three connecting arms, two of which are assembled into a frame-like structure by appropriate design, whereby the eccentric engages one meeting point and the third connecting arm engages the other meeting point, said third arm being rigidly connected with one lever arm of the double-armed rocker arm. The connecting arms are each provided with a film hinge, of which two hinges lie on a common middle/bending axis which intersects the lengthwise axis of the double-armed rocker arm.
