ラ雲台のカウンターバランス機構。 In a camera pan head, a camera mount 9 is supported by a shaft 13 on both side plates 8, 8' of the base 3, which is formed to be rotatable in the horizontal direction, and is rotatable in the vertical direction. Box-shaped space 2 inside
1, and a cam 1 that slides in a direction perpendicular to the center line of the shaft 13 is fitted in the space 21.
The box-shaped space 21 is attached to both side plates 8, 8' on a horizontal straight line passing through the center of the shaft 13 between the cam wall surface 1a of the cam wall 1a and the inner wall of the box-shaped space 21 facing the wall surface. A counterbalance mechanism for a camera pan head, characterized in that a roller mechanism passing through the camera pan head 21 is provided, a spring that constantly presses the cam wall surface 1a against the roller mechanism, and a balance adjustment mechanism for adjusting the repulsive force of the spring. .
