Abstract: A hydroelectric power generation apparatus includes a hydroelectric power generation module, a beam as a supporting part, and a fixing part. The hydroelectric power generation module includes a rotary blade and a power generator that generates power by rotation of the rotary blade. The supporting part supports the hydroelectric power generation module. The fixing part fixes the supporting part to a water channel. The fixing part includes a bolt to press a surface of a wall portion of the water channel to fix the supporting part to the water channel. The hydroelectric power generation apparatus can dispense with a work performed around the water channel to install the apparatus and also be relocated easily and inexpensively.
