Although in a driving tool operating by an electric motor as a drive source, according to a background art, there has been provided a technology of engaging projected streaks having V-shapes in cross sections with a plurality of V grooves in order to achieve a high striking force by efficiently transmitting a rotational force of a drive wheel to a driver support base, high working accuracy is needed in that case, and therefore, according to the invention, it is enable to achieve a large striking force without need of high working accuracy. A driver support base (20) is provided with a transmitting portion (20b) having a V-shape in cross section, the driver support base (20) is pressed by a press member (41) to cause the transmitting portion (20b) to wedge between a pair of left and right drive wheels (30, 30), so that a friction force is increased to achieved a large drive force of the driver support base (20).
