そして、本発明に係る風車装置10は、回転翼13の羽根12が風を受けることで、以下のような回転動作を行う。まず、風車装置10の回転停止時には、移動体変位室内に設けられた移動体は、移動体変位室の底面の傾斜により、移動体変位室の下位である中心付近に位置する。すなわち、風車装置10の回転停止時には、移動体は、風車装置10の回転中心軸付近に位置する。これにより、風車装置10の回転開始時おける慣性モーメントを小さくすることができるので、風車装置10の自己起動性を向上させることができる。
そして、回転翼13の羽根12が風を受けて風車装置10が回転を開始すると、移動体変位室の中心付近に位置していた移動体は、遠心力により、移動体変位室内を、回転軸11に直交する平面において回転軸11から放射状に外側に向かう方向に、移動体変位室の底面に沿って移動する。かかる場合に、移動体は、移動体変位室に設けられた仕切り部材29との摩擦により、回転軸11に直交する平面において回転軸11から放射状に外側に向かう方向に移動しやすくなっている。そして、移動体変位室内に設けられた移動体が、遠心力により、移動体変位室内を、回転軸11に直交する平面において回転軸11から放射状に外側に向かう方向に移動すればするほど、風車装置10の慣性モーメントは大きくなる。すなわち、風車装置10の回転中における慣性モーメントを大きくすることができるので、風車装置10の回転を停止し難くすることができる。
（請求項２）

First, when the rotation stop of the wind turbine device 10, the mobile has been found provided on the moving body displacement chamber is the inclination of the bottom surface of the movable body displacement chamber, located near the center is subordinate mobile displacement chamber. That is, when the rotation of the windmill device 10 is stopped, the moving body is positioned near the rotation center axis of the windmill device 10. Thereby, since the moment of inertia at the start of rotation of the windmill device 10 can be reduced, the self-startability of the windmill device 10 can be improved.
When the blades 12 of the rotor blades 13 Windmill apparatus 10 before the wind starts to rotate, moving body was located near the center of the moving object displacement chamber by centrifugal force, the moving body displacement chamber, the rotary shaft in a direction from the rotary shaft 11 toward the outside radially in a plane perpendicular to the 11, it moves along the bottom surface of the movable body displacement chamber. In such a case, the moving body is likely to move radially outward from the rotating shaft 11 on a plane orthogonal to the rotating shaft 11 due to friction with the partition member 29 provided in the moving body displacement chamber . Then, the moving body was found provided on the moving body displacement chamber is, by centrifugal force, the moving body displacement chamber, the rotary shaft 11 in a plane perpendicular to the rotational shaft 11 the more you move in a direction towards the radially outward In addition, the moment of inertia of the wind turbine device 10 increases.
