<p><P>PROBLEM TO BE SOLVED: To provide a speed reducing mechanism capable of effectively suppressing inclination of an output shaft. <P>SOLUTION: A speed reducing mechanism 1 includes: an input shaft 2 and a sun gear 3 coupled to the input shaft 2 and driven thereby; a planetary gear 4 disposed in the outer circumferential side of the sun gear 3 and engaged with the sun gear 3; a planetary carrier 5 supporting the planetary gear 4; an internal gear 6 located in the outer circumferential side of the planetary gear 4 and engaged with the planetary gear 4; an output shaft 7 coupled to the internal gear 6 and driven thereby; a bearing 8 rotatably supporting the output shaft 7; and a casing 9 supporting the bearing 8 and externally covering the sun gear 3, the planetary gear 4, the planetary carrier 5 and the internal gear 6. The mechanism also includes an imparting means 11 that imparts supporting force directed from the radially outside to the inside to the outer circumferential face of the internal gear 6. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
