Disclosed are a rack and pinion type power transmission and a driving apparatus of an embroidery frame of an embroidery machine having the same. The gear teeth, which are engaged with the engaging member connected to the power source, are formed in the lower side of the a single movable frame, to which the embroidery frame is fixed, so as to directly move the movable frame, so that uniform driving force is transmitted to the embroidery frame during the movements of the embroidery frame. Thus, the high reliable and steady movement is performed. The driving apparatus includes any one of the X- and Y-directional movement mechanisms. The mechanism includes a fixed frame installed to a beam-body of the sewing machine, a movable frame movably installed on the fixed frame and having gear teeth, and a movable frame movement mechanism engaged with the gear teeth to reciprocate the movable frame.
