<p>A driver using an electric motor as the drive source. In a conventional technique, in order to obtain high driving force by efficiently transmitting rotational power of a drive wheel to a driver support table, projections with a V-shaped cross-section are meshed with V grooves. However, the technique requires high working accuracy. A driver of the invention provides high driving force without requiring such high working accuracy. A transmission section (20b) with a V-shaped cross-section is provided on a driver support table (20). The driver support table (20) is pressed by a pressing member (41) to cause the transmission section (20b) to be forced between a left and right pair of drive wheels (30, 30). This increases friction force to obtain high driving force of the driver support table (20).</p> |
