The present invention provides a drive apparatus that is compact in size, low in cost, allows the attaining of a high degree of accuracy as well as high-speed driving, suppresses the production of noise, and demonstrates favorable ease of assembly when incorporating within machine tools and so on. The present invention is able to obtain the effects of reduction of costs, high accuracy and high-speed driving as a result providing a torque generation device on a slider guided by a track rail, attaching a drive roller to the output shaft of the torque generation device, and said drive roller rolling along the track rail. In addition, the above-mentioned effect of improved ease of assembly is obtained by attaching the torque generation device facing horizontally on the side of the slider.
