<P>PROBLEM TO BE SOLVED: To provide a belt type reduction gear that can exhibit high silence performance while achieving miniaturization. <P>SOLUTION: The belt type reduction gear includes: an input pulley 12 for input of a rotational drive force; an output pulley 14 which is formed larger in diameter than the input pulley 12, reduces the rotational drive force that is input to the input pulley 12, and outputs it; and one endless belt 17 which is formed in an endless manner, and bridged from the input pulley 12 toward the output pulley 14. Then, the input pulley 12 and the output pulley 14 are arranged so as to be displaced from each other in the rotational axial direction. Furthermore, a contour circle of the input pulley 12 and a contour circle of the output pulley 14 are arranged so as to overlap with each other at least at one part viewing from the rotational axial direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
