PROBLEM TO BE SOLVED: To provide a power transmission apparatus which can be miniaturized and whose cost can be reduced. SOLUTION: The power transmission apparatus 1 includes an input gear 3 which inputs a driving force, an output gear 5 which engages with the input gear 3, an output shaft 7 which is provided integrally rotatably with the output gear 5, a casing 9 which accommodates the output shaft 7 and a bearing 11 which supports the output shaft 7 rotatably to the casing 9. In this apparatus 1, the bearing 11 includes an outer race 13 which is fixed in contact with the casing 9, an inner race 15 which slides on the output shaft 7, and a pair of balls 17, 19 which are arranged between the outer race 13 and the inner race 15 to support the inner race 15 rotatably. A fixing member 21, which contacts an axial end of the outer race 13 and determines the position of the bearing 11 in the axial direction, is fixed on the casing 9. COPYRIGHT: (C)2011,JPO&INPIT |
