Amendment December 19, 1981 The name of the invention is amended as follows. Title of the invention Planetary gear device for high load transmission The scope of the utility model registration claims and the brief description of the drawings are amended as follows.

[Claims for Utility Model Registration] A fixed sun gear and a driven sun gear fixed to a driven shaft are meshed with each of the sun gears.
A planetary gear made up of two integrally formed gears is rotatably and slidably supported by a pin implanted in a drive lever provided on the drive side ,
In a reduction gear of the type that rotates while being supported by a spring so as to be spaced apart from the drive lever side , the end surfaces of the two integrally formed planetary gears on the drive lever side are connected to a fixed sun gear and a driven sun gear. The position of the two sun gears is determined by a spacer provided on the fixed sun gear side so that the end face of the gear on the drive lever side is offset to the side opposite to the drive lever, and the end faces of the two planetary gears on the drive lever side mesh with each other .
1. A planetary gear device for high load transmission, characterized in that the gears are maintained in a meshed state shifted toward the spacer side from the drive lever side end surface .

Claims (1)

[Scope of utility model registration request] A planetary gear consisting of two gears meshing with each of the sun gears surrounds a fixed sun gear and a driven sun gear fixed to a driven shaft, and is pressed by a spring so as to be separated from the drive lever. In a type of reduction gear that is supported and rotates, a spacer is provided on the fixed sun gear side so that the tooth surfaces of the two planetary gears are biased toward the opposite side of the drive lever from the tooth end surfaces of the fixed sun gear and the driven sun gear. 1. A planetary gear device for high load transmission, characterized in that the planetary gears are positioned so that the end surfaces of the planetary gears are maintained in a meshed state shifted from the end surfaces of the sun gears.
