Fluid activating device

A fluid activating device comprising:

• a shaft in a cylindrical columnar shape;
• a first tubular body provided with a first hollow part to accommodate the shaft with a predetermined interval between an inner peripheral surface of the first hollow part and an outer peripheral surface of the shaft;
• multiple first blades that are provided between the outer peripheral surface of the shaft and an inner peripheral surface of the second tubular body while forming a first flow path extending spirally from one end side toward another end side of the first tubular body, and that generate a turbulent flow in fluid flowing through the first flow path;
• multiple first ribs that are provided on an inner peripheral surface of the first tubular body and that are each composed of a ridge extending in an axial direction of the shaft;
• a second tubular body provided with a second hollow part to accommodate the first tubular body with a predetermined interval between an inner peripheral surface of the second hollow part and the outer peripheral surface of the shaft;
• multiple second blades that are provided between an outer peripheral surface of the first tubular body and the inner peripheral surface of the second tubular body while forming a second flow path extending spirally from one end side toward another end side of the second tubular body, and that generate a turbulent flow in fluid flowing through the second flow path;
• and
• multiple second ribs that are provided on the inner peripheral surface of the second tubular body and that are each composed of a ridge extending in the axial direction of the shaft.
