A rotor for a wind/water power machine can reduce fluid resistance. The rotor (1A) includes a hub (10A) and blade (20A). In a projection plane perpendicular to the central axis of rotation of the rotor, at least a portion of the leading edge (31A) of the blade protrudes forward in the rotational direction of the rotor with respect to a first line segment (L1A), the tip (32A) of the leading edge protrusion is positioned outward in the radial direction of the rotor from the hub peripheral edge by 0.4-0.6 times the blade length, and at least a portion of a section (34A) of the leading edge of the blade extending from the inward end in the radial direction to the tip of the leading edge protrusion is curved or bent to be convex backward in the rotational direction of the rotor with respect to a second line segment (L2A). |
