<P>PROBLEM TO BE SOLVED: To facilitate maintenance regardless of simple structure and inexpensive manufacture. <P>SOLUTION: The output case 37 of a reduction gear 31 is integrally rotatably connected to a windmill blade 11 through an inward flange 50, however, the output case 37 surrounds a crankshaft 33 and a deceleration section 47 from a periphery and has a comparatively large diameter, therefore, the output case 37 has high strength, and deflection during transmitting rotational force is reduced. Besides, the output case 37 is positioned coaxially with the windmill blade 11, therefore, lateral force does not act on the deceleration section 47, contact and abrasion of teeth (the external tooth of a pinion 36 and an internal tooth pin 38) of the deceleration section 47 are approximately uniformalized over the whole of tooth width, and the life of teeth is extended longer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
