A pump device may include a first case provided with a circular ring-shaped protruded part, a second case provided with a circular ring-shaped stepped part into which the circular ring-shaped protruded part is coaxially inserted, an O-ring which is mounted on a circular outer peripheral face of the circular ring-shaped protruded part and is crushed between the circular outer peripheral face of the circular ring-shaped protruded part and a circular inner peripheral face of the circular ring-shaped stepped part in a direction perpendicular to an axial line of the circular ring-shaped protruded part, and a turning prevention mechanism which prevents the first case and the second case from being relatively turned to each other around the axial line when the circular ring-shaped protruded part of the first case is inserted into the circular ring-shaped stepped part of the second case to form the pump chamber.

A flow meter may include a case body formed with a fluid space in its inside, an impeller disposed in the fluid space, a detected part integrally provided in the impeller, a detecting part provided with detecting terminals for detecting the detected part, terminal pins which is provided with terminal contact parts, which are electrically connected with the detecting terminals of the detecting part, and connector parts with which a connector for outputting an electric signal to an outside is connected, and a holder to which the terminal pins are fixed and which is detachably held by the case body through a holder holding part provided in the case body. The detecting part and the terminal contact parts are held between the case body and the holder by attaching the holder to the case body so that the terminal contact parts are contacted with the detecting terminals.

A hydraulic power generating device may include a power generating hydraulic turbine having a plurality of first blades projected on an outer peripheral side and a cylindrical plate part which may be coaxially structured with a rotating center axial line of the power generating hydraulic turbine at a position adjacent in an axial direction to the first blades, and an ejection port for ejecting water may be opened both to the first blade and to the cylindrical plate part. Further, hydraulic power generating device may include a power generating hydraulic turbine having a hollow cylindrical body, a first cylindrical radial bearing and a second cylindrical radial bearing. The second radial bearing may be positioned at a second end part of the hollow cylindrical body with a shaft hole of the first radial bearing as the reference.
