<P>PROBLEM TO BE SOLVED: To provide technology to suppress the occurrence of error in rotational speed due to error in shape of each gear in driving force transmission using a plurality of gears. <P>SOLUTION: The driving force transmission device includes: a first gear that is rotationally driven by having the driving force transmitted, in which a plurality of first dimension stipulating parts giving specified influence to the dimension of the first gear in the direction of a rotational radius are provided in different positions in the rotating direction of the first gear; and a second gear that is rotationally driven by having the driving force transmitted from the first gear by being engaged to the first gear, in which a plurality of second dimension stipulating parts giving specified influence to the dimension of the second gear in the direction of the rotating radius are provided in positions on a matching phase with the first dimension stipulating parts in the rotational direction of the second gear when engaged with the first gear. <P>COPYRIGHT: (C)2008,JPO&INPIT |
