The subject of the present invention is to provide a blade end portion protecting bag which is fit onto an end portion of a plurality of blades for protecting the blade end portion from damage when the plurality of the blades are hoisted with a rotor head to the position of an upper nacelle in assembling a wind turbine, the protecting bag having such structure that a rope joint for connecting a control rope is hard to break and therefore the durability of the rope joint portion is improved; and a rotor installing method for installing the rotor to the nacelle with the protecting bag fit onto the blade. A blade end portion protecting bag which is fit onto an end portion of a plurality of blades in installing the blades 8 to the nacelle supported on the top of a tower 2, the protecting bag comprising an end bag 10 fit onto the end portion of at least one of a plurality of the blades 8 to cover the same in a predetermined length from the end of the blade, at least two belt-like members 11a to 11e disposed to radiate from a center portion P and fixed to the outer surface of the end bag 10 in its circumference, wherein the belt-like members are bunched up at the center portion, and a control rope is connected to the belt-like members at center portion P.
