To provide hydraulic generating equipment which dispenses with work for damming up a river and large-scale construction work, which does not destroy natural environments such as an ecological system and a landscape, and which makes power generation efficiency proper.

Hydraulic generating equipment includes a generator 11 which is connected to a rotating shaft 10 of a disk-like rotating hub 13, and a water turbine which comprises a plurality of hood-variable water turbines 9 arranged radially from the center of the rotating hub 13. The hood-variable water turbine 9 is formed in such a manner as to be freely opened/closed on a hinge 15 attached to the rotating hub 13, by combining a pair of water receiving and holding plates 34 together. The hood-variable water turbine 9 is formed so as to receive flowing water by being expanded when receiving the flowing water and to reduce water pressure resistance applied from a rotational direction by being closed in the latter half of rotation.
