Abstract:
1. A tripod head comprising: a mounting which is tiltable and allows a filming apparatus to be mounted thereon; a counterbalancing mechanism comprising a spring and being configured to generate a resilient force on the spring so as to counterbalance with a rotation moment generated when the filming apparatus to be mounted on the mounting tilts; and a resilient force adjusting mechanism configured to accommodate a weight of the filming apparatus and impart a resilient force in advance on the spring of the counterbalancing mechanism, wherein the resilient force adjusting mechanism includes a rotating operation part, a cam coupled in between the rotating operation part and the spring and configured to slide with a rotation of the rotating operation part, and a cam follower in contact with a cam surface of the cam, the cam follower being supported by the counterbalancing mechanism, and the counterbalancing mechanism is configured in such a manner that a magnitude of the resilient force imparted on the spring varies depending on the position where the cam follower contacts the cam.
