PURPOSE: To provide an antenna angle adjusting device which can quickly and finely adjust the directive angle of an antenna.

CONSTITUTION: The fine and rough adjustment mechanisms are provided between an antenna reflector and an antenna support so that the turning position of the antenna reflector is adjusted to the antenna support. For instance, the rough adjustment mechanism A consists of a rough adjustment screw rod 2 which is fixed at the antenna support side 12 through a single end of the rod 2, a pair of adjustment nuts 3 and 4 which are screwed into the rod 2, and a rough adjustment bracket 5 which is held between both nuts 3 and 4 in the axial direction. Meanwhile the fine adjustment mechanism B consists of a fine adjustment rod 6 which is connected to the antenna reflector side 13 through a single end of the rod 6, and a worm wheel, 7, a worm 8 and a handle 9 which are provided to the bracket 5 and engaged with the rod 6.
