A head for a tripod support or the like comprises a panning braking device having a plurality of braking units (5,6) with different braking forces which is supported on a panning shaft (2), and a torque switchover mechanism (10,11,14) allowing to freely switch over torque on the side of said braking units (5, 6); a weight balancer having a plurality of spring units (26,27), in which one or a plurality of spiral springs (24,25) with different elastic forces are incorporated, supported on a tilting shaft (22) and a righting moment switchover mechanism (42,43,46,47,52) allowing to freely switch over a righting moment against the tilting on the sides of the spring units (26,27); a tilting braking device having a plurality of braking units (60,61) with different braking forces which is supported on said tilting shaft (22), and a torque switchover mechanism allowing to freely switch over torque on the sides of the braking units (60,61); and a sliding plate device having a set spring (71;71a,71b) capable of freely floating and sinking, said set spring (71;71a,71b) being in contact with one of the side end surfaces of the sliding plate (65) 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 (66), and supporting said sliding plate (65) under pressure. <IMAGE> |
