用雌ねじ加工を施した空中線装置主軸と、同じく
雄ねじ加工を施した油圧シリンダを連結し、この
油圧シリンダの直線運動を主軸の回転運動に変え
ることによつて、新たに電源やモータを装備する
ことなく、車輌既設の油圧シリンダを用いて空中
線装置の回転駆動を行なうことを特徴とした車載
用空中線装置駆動機構。 The main shaft of the antenna device, which is held so that only rotational movement is possible and is machined with a female thread for a ball screw, is connected to a hydraulic cylinder, which is also threaded with a male thread, and the linear movement of this hydraulic cylinder is converted into the rotational movement of the main shaft. Therefore, an on-vehicle antenna device drive mechanism is characterized in that the antenna device is rotationally driven using a hydraulic cylinder already installed in the vehicle without installing a new power source or motor.
