Disclosed herein is an aerogenerator having a rotation support unit for facilitating rotation of a rotational body. The aerogenerator includes a support pillar, a rotational body, vanes, a rotating force transmission unit, a generating unit and a rotation support unit. The support pillar has a hollow space therein and has a support extension on the upper end thereof. The rotational body is provided on the upper end of the support pillar so as to be rotatable using the rotation support unit. The vanes are provided on opposite ends of the rotational body. The rotating force transmission unit transmits rotating force of the vanes to the generating unit. In the present invention, the rotation support unit comprises a rotating plate which is provided between the rotational body and the support pillar, and first rollers which are provided in the rotating plate and are in contact with the rotational body and the support extension. The rotation support unit further comprises second rollers which are provided under the rotating plate and are in contact with the inner surface of the hollow space of the support pillar. Therefore, the rotational body can easily rotate on the upper end of the support pillar by the first rollers, and the rotational plate can be prevented from being separated from the upper end of the support pillar by the second rollers.

1. An aerogenerator, comprising: a support pillar placed upright on ground, the support pillar having a hollow space therein, with a support extension extending a predetermined distance from an upper end of the support pillar inwards such that the hollow space is open on the upper end of the support pillar through a center of the support extension;a rotational body, provided on the upper end of the support pillar, which is rotatable on a rotation support unit having rollers, the rotational body including vanes provided on opposite ends of the rotational body, the vanes being rotatable by wind; anda rotating force transmission unit to transmit a rotating force of the vanes to a generating unit,wherein the rotation support unit includes:a rotating plate provided between the rotational body and the support pillar;first rollers provided at a perimeter of the rotating plate at positions spaced apart from each other at regular intervals around the circumference of the rotating plate, the first rollers in contact with a lower surface of the rotational body and an upper surface of the support extension of the support pillar; andsecond rollers provided under a perimeter of a lower surface of the rotating plate at positions spaced apart from each other at regular intervals around the circumference of the rotating plate, the second rollers in contact with an inner surface of the hollow space of the support pillar,whereby the rotational body easily rotates on the upper surface of the support extension of the support pillar because of the first rollers, and the rotational plate is prevented from being separated from the upper end of the support pillar by the second rollers,wherein roller support shafts are fastened to the lower surface of the rotating plate and bent towards the inner surface of the support pillar, and the second rollers are rotatably mounted on ends of the respective roller support shafts and are in contact with the inner surface of the support pillar. 2. An aerogenerator, comprising: a support pillar placed upright on ground, the support pillar having a hollow space therein, with a support extension extending a predetermined distance from an upper end of the support pillar inwards such that the hollow space is open on the upper end of the support pillar through a center of the support extension;a rotational body, provided on the upper end of the support pillar, which is rotatable on a rotation support unit having rollers, the rotational body including vanes provided on opposite ends of the rotational body, the vanes being rotatable by wind; anda rotating force transmission unit to transmit a rotating force of the vanes to a generating unit,wherein the rotation support unit includes:a rotating plate provided between the rotational body and the support pillar;first rollers provided at a perimeter of the rotating plate at positions spaced apart from each other at regular intervals around the circumference of the rotating plate, the first rollers in contact with a lower surface of the rotational body and an upper surface of the support extension of the support pillar; andsecond rollers provided under a perimeter of a lower surface of the rotating plate at positions spaced apart from each other at regular intervals around the circumference of the rotating plate, the second rollers in contact with an inner surface of the hollow space of the support pillar,whereby the rotational body easily rotates on the upper surface of the support extension of the support pillar because of the first rollers, and the rotational plate is prevented from being separated from the upper end of the support pillar by the second rollers,wherein a guide protrusion is provided under a lower surface of the support extension of the support pillar and extends around the circumference of the support extension, wherein the second rollers are in contact with one surface of the guide protrusion and move along the guide protrusion. 3. The aerogenerator as set forth in claim 2, wherein a second roller guide groove is formed on the surface of the guide protrusion which is in contact with the second rollers, so that the second rollers are guided by the second roller guide groove.
