PURPOSE:To attain continuous communication without hindrance by eliminating the restriction of rotation of a movable part for a horizontal stabilizing base due to a cable in an antenna directing device for a mobile object. CONSTITUTION:The antenna directing device for the mobile object is constituted in which a horizontal stabilizing base 3 provided on a support 2 fixed to the mobile object 1, tiltably in all directions and freely turnably around its longitudinal shaft, and an antenna 4 provided on the horizontal stabilizing base 3 whose elevating angle is freely taken are provided. The device is provided with a longitudinal shaft rotating section 6 composed of a stationary shaft 8 and a rotary shaft 9 inserted to each other at their inside and outside, and a slip ring mechanism 10 connected to a cable freely rotationably and a coaxial rotary joint 11 are provided between the stationary shaft 8 and the rotary shaft 9 of the longitudinal shaft rotating section 6. |
