A tripod head comprises a panning braking device having a plurality of braking units with different braking forces which is supported on a panning shaft, and a torque switchover mechanism allowing to freely switch over torque on the side of said braking units; a weight balancer having a plurality of spring units, in which one or a plurality of spiral springs with different elastic forces are incorporated, supported on a tilting shaft and a righting moment switchover mechanism allowing to freely switch over a righting moment against the tilting on the sides of the spring units; a tilting braking device having a plurality of braking units with different braking forces which is supported on said tilting shaft, and a torque switchover mechanism allowing to freely switch over torque on the sides of the braking units; and a sliding plate device having a set spring capable of floating and sinking, the set spring being in contact with one of the side end surfaces of the sliding plate for securing a device such as a camera, a video camera, a movie camera or the like which is slidable in the longitudinal direction against a camera stand, and supporting the sliding plate under pressure.
