Abstract: A panhead (11) has a base body (20), a tilting body (21), and a camera mount (41). The base body (20) is adapted to be connected to a leg system 12. The tilting body (21) can be adjustably rotated around a rotation center axis (X) that horizontally extends in the lateral direction. The camera mount (41) can be adjustably rotated around a rotation center axis (A) that horizontally extends in the fore-and-aft direction and coincides with the axial direction of a side-tilting shaft. The rotation center axis (A) of the camera mount (41) approximately coincides with a lateral-dimension-bisecting line (B) of the base body (20) as viewed from the top. The side-tilting shaft is disposed approximately below a camera fixing screw (59) of the camera mount (41).

Abstract: A foundation comprising (1) a cylindrical shell made of a cast-in-place concrete placed into a ring-like groove which is formed by excavation of the soil at the place of installation of the foundation, leaving a columnar soil located radially inward with respect to the ring-like groove without discharging the soil, and (2) an internal solidified soil formed by solidifying the columnar soil surrounded by the cylindrical shell with a chemical hardener, and a construction method therefor.
