PURPOSE: A planetary gear torque increasing apparatus is provided to obtain great output torque without reducing speed of a motor, thereby improving the productivity and reducing electric energy. CONSTITUTION: A planetary gear torque increasing apparatus(1) includes an input side(100) formed with a first internal gear(140) fixed at the inner periphery of a first butt end(110) mounted on one side of a cylindrical body(10), a first sun gear(130) engaged with the inside of the first internal gear and coupled with an input shaft(131) for inputting rotation of a motor, a plurality of first pinion gears(140) engaged with the inside of the first internal gear radially, and a second internal gear(150) coupled with a rear end of a pinion shaft for be rotated by the revolution of the first pinion gears when the plurality of the first pinion gears are rotated by the rotation of the first sun gear and are revolved by the first internal gear; and an output side(200) formed with a plurality of second pinion gears(220) mounted at a second butt end(210) and engaged with the inside of the second internal gears radially, and a second sun gear(230) engaged with the plurality of second pinion gears on a central line for being fast rotated by fast rotation of the second pinion gears.
