Abstract
An electric driving unit is provided with a bracket. A slide plate is mounted on the bracket for sliding movement in a direction perpendicular to an axis of an output shaft of the electric driving unit. A first pivot holder is secured to one of side walls of the slide plate. A second pivot holder is mounted on the other side wall such that the second pivot holder can be adjusted in an advancing and retracting manner with respect to the first pivot holder. The first and second pivot holders are arranged such that they can hold opposite ends of any pivot shaft for various jacks even if the length of the shaft is different. With this arrangement, it is possible to provide an electric power tool for driving a jack which can be used for various types of jacks having pivot shafts of different lengths.
