Abstract

PURPOSE:To make a blade angle variable only when a hub cover is rotated by bringing an inner surface of the hub cover in contact with a front periphral surface of a hub free of rotation and slide motion, and inserting a pin of a blade root part into a hole of the hub cover free of rotation as well. CONSTITUTION:At the central part of a hub 1, there is provided with a boss part 4 which has a hole 3 into which a shaft 2 of an electric motor is inserted, and a plurally of holes 5 for blade mounting are formed in a peripheral side wall. A hub cover 8, inserting a bearing 7 into the center, is brought into contact with a front peripheral surface 6 of the hub 6 free of rotation so as to cause the inner surface 9 to be slidden. A blade 12 is rotatably attached to the hole 5 via a mounting clamp 11 having a bearing 10 at the inner part of the hub 1. In addition, a pin 14 is projectingly at the side of the hub 1 in a root part 13 of the blade 12, and this pin 14 is rotatably inserted into a hole installed on the circumference of the hub cover 8 at the same pitch as much as the same number as the blade 12.
