動調整機構。 In an aerial work vehicle in which a boom is attached to the vehicle body so that it can be raised/lowered, extended/contracted, and rotated, and a work platform is connected to the tip of the boom so as to be horizontally rotatable, a support shaft is attached to the side wall of the work platform. The sensor arm is connected so that it can rotate horizontally, so that the sensor arm is always biased toward the work wall. A potentiometer is connected to the support shaft, and the tip of the sensor arm is The support plate is connected to the base fixed to the universal yoke so as to be rotatable in the horizontal and vertical directions through yoke pins that protrude vertically from the universal yoke and yoke pins that protrude horizontally. The ball caster is fixed to the support plate so that it is always held parallel to the base through a balancing action, and the yoke pins that protrude in the vertical direction and the yoke pins that protrude in the horizontal direction are respectively attached to the support plate. An automatic working distance adjustment mechanism for an aerial work vehicle consisting of connected potentiometers.
