<p>The present invention is an outer rotor type motor, and a thin gear motor for transferring rotation of a motor shaft of the outer rotor type motor to an output shaft via a reduction mechanism that uses a planetary two-step gear comprising a large gear and a small gear provided in a planetary gear accommodation case and having the same axial center, wherein: the planetary two-step gear is aligned in only one step; the thin gear motor is configured using a non-integral multiple of the gear ratio of the large gear and small gear of the planetary two-step gear; and it is possible to obtain a thin gear motor and a muscular strength assistance device using the thin gear motor in which high torque output is achieved, the devices can be made thin, small, and lightweight, the number of selectable gear ratios can be remarkably increased, the degree of freedom in the design can be vastly improved, and costs can be vastly reduced.</p> |
