PROBLEM TO BE SOLVED: To provide a directional antenna driving device for a transmission/ reception directional antenna with high reliability which is provided with durability without generating noise. SOLUTION: The directional antenna driving device turns the transmission or reception directional antenna in a prescribed direction. The device is provided with a first rotary body (substrate 23) for rotating the directional antenna 1a in a horizontal direction and a second rotary body 25 for setting the vertical direction angle of the directional antenna with a rotary axis being the same as that of the first rotary body as a center. The directional antenna driving device sets the azimuth of the directional antenna and the vertical direction angle by rotating the first and the second rotary bodies 23 and 25.
