As shown in FIG. 5, the blades 3 are configured to be arranged symmetrically around the cylindrical rotating body 4 when the vertical axis wind power generator 1 is viewed from above. In the present embodiment, the number of blades 3 is two, but may be three or more. Also, one surface 3a and the other surface 3b of the two blades 3 shown in FIG. 5 may be reversed.

筒状回転体４は、断面が円の筒であり、中心部に板状のフランジ５を水平に備えている。また、筒状回転体４、フランジ５及び羽根３のそれぞれの上下方向の中心線が一致する（図２における一点鎖線参照）ように、筒状回転体４、フランジ５及び羽根３が配置されている。つまり、図２に示すように、長さＬの筒状回転体４の一端からＬ／２の距離にある位置を中心線として筒状回転体４、フランジ５及び羽根３が配置されている。

次に、垂直軸型風力発電装置１の作用について説明する。
風を受けた羽根３は、支持部材７を介して風力による動力を筒状回転体４に伝達する。筒状回転体４に取り付けられた支持部材７や羽根３は、図２における一点鎖線を中心として、重心のバランスをとって配置され、かつ、筒状回転体４の重心位置と軸受の設置位置との距離が小さいので、筒状回転体４は、周方向にバランスよく回転する。そして、筒状回転体４は、筒状回転体４内部中央に設けられたフランジ５、６を介して、回転力を回転軸２に伝達する。回転軸２は、筒８内部の軸受９、１０、１１によって回転自在に支持されながら回転し、発電装置１２に回転力を伝達する。その結果、発電装置１２によって発電される。 Next, the operation of the vertical axis wind power generator 1 will be described.
The blades 3 that have received the wind transmit the power of the wind force to the cylindrical rotating body 4 via the support member 7. The support member 7 and the blade 3 attached to the cylindrical rotating body 4 are arranged in a balanced manner with respect to the center of gravity around the one-dot chain line in FIG. 2, and the center of gravity position of the cylindrical rotating body 4 and the installation position of the bearing are arranged. Therefore, the cylindrical rotating body 4 rotates in a balanced manner in the circumferential direction. The cylindrical rotating body 4 transmits the rotational force to the rotating shaft 2 via flanges 5 and 6 provided at the center inside the cylindrical rotating body 4. The rotating shaft 2 rotates while being rotatably supported by the bearings 9, 10, 11 inside the cylinder 8, and transmits the rotational force to the power generation device 12. As a result, power is generated by the power generation device 12.

本実施形態によれば、筒状回転体４に取り付けられた支持部材７や羽根３は、図２における一点鎖線を中心として、重心のバランスをとって配置され、かつ、筒状回転体４の重心位置と軸受の設置位置との距離を小さくするので、筒状回転体４は、周方向にバランスよく回転し、回転軸２に横風などによる水平方向の曲げモーメントを低減できる。その結果、回転軸を太くしなくともよいため、軸受の径を小さくできるので、メカロスを抑止することができ、効率のよい発電が可能であり、しかも小型で軽量の垂直軸型風力発電装置を提供できる。   According to the present embodiment, the support member 7 and the blade 3 attached to the cylindrical rotator 4 are arranged with a balance of the center of gravity around the one-dot chain line in FIG. Since the distance between the position of the center of gravity and the installation position of the bearing is reduced, the cylindrical rotating body 4 rotates in a balanced manner in the circumferential direction, and the bending moment in the horizontal direction due to a cross wind or the like can be reduced on the rotating shaft 2. As a result, the diameter of the bearing can be reduced because the rotating shaft does not need to be thick, so that mechanical loss can be suppressed, efficient power generation is possible, and a small and lightweight vertical axis wind power generator is provided. Can be provided.
