PROBLEM TO BE SOLVED: To provide a turbine and a hydroelectric power installation having the turbine which is of a simplified structure and affords greater power output. SOLUTION: This turbine for the hydroelectric power installation generates electrical energy. The turbine includes: a rotor (4); a plurality of turbine blades (1); and a guide mechanism (6) which is disposed behind the rotor in a cross flow direction and which has a plurality of blades (5) functioning as a turbine support mechanism and inclined with respect to the cross flow direction. The pitch angle of each turbine blade (1) of the rotor (4) is adapted to be variable. The turbine is formed into an upstream rotor turbine so that the turbine blades (1) obtain an incoming flow not substantially disturbed in the cross flow direction by the turbine.
