In a small-sized hydroelectric power generating apparatus in which a waterwheel

3

arranged in a fluid path and rotating with passage of a prescribed flow rate of fluid, a rotating body

4

coupled with the waterwheel and rotating therewith is used as a rotor portion arranged oppositely to a stator portion

6

, and the rotor portion is rotated relatively to the stator portion

6

with passage of the fluid to generate electric power, the small-sized hydroelectric generation includes a continuous internal space formed when a first case

1

and a second case

5

are fit to each other, said first case having an inlet

12

and an outlet

13

of said fluid path and said second case having the internal space which communicates with said inlet and outlet and in which said rotating body is arranged and separating the internal space from the stator portion, wherein a concave portion

14

is provided at a fitting portion between said first case and said second case; an opposite wall

5

a

opposite to the inner wall of said concave portion or the outer wall of said convex portion is provided at the fitting portion between said first case and said second case; a ring-shaped sealing member

8

is provided which is interposed between said opposite wall and the inner wall of said concave portion

14

in a direction orthogonal to the direction of fitting said second case into said first case, and said first case

1

and said second case

5

are provided with supporting portions

11

b

, 5

f

, respectively which support both ends of a shaft

7

supporting said rotating body

4.
