Abstract

PURPOSE: To prevent a wing of the wind mill from fatigue failure and to improve the efficiency of the wind-mill by a method wherein a boom is divided into a front and a rear parts and a spring is interposed between them.
CONSTITUTION: The boom 32 is divided into a front boom 23 and a rear one 24 and a spring 29 is interposed between them. Since the sail wing of a vertical shaft type wind-mill is expansible and initial tension can be provided, the wing surface can be made without sagging, fatigue failure of the wing due to the flapping of the wing surface can be prevented, perfect blade form is obtainable and wind mill efficiency can be improved.
