PROBLEM TO BE SOLVED: To obtain an antenna apparatus having a rotation stopping mechanism in which a failure hardly occurs with few number of parts by rotating an antenna in a limited range of rotation angle. SOLUTION: A movable side block 10 is formed on the periphery (a) of an azimuth shaft 3 center. In a cam 12, a movable side connecting part 13 is provided on the periphery (a), and a securing side connecting part 14 is provided on the periphery (b) of the azimuth shaft 3 center. A securing side block 15 is located on the periphery (b). The movable side block 10 is brought into contact with the movable side connecting part 13 provided in the cam 12 by the rotation of the movable part 8 around the azimuth shaft 3. Further, the securing side connecting part 14 provided in the cam 12 is brought into contact with the securing side block 15 by further rotating the cam 12 together with the movable side.
