装置。[Claims for Utility Model Registration] The input shaft is provided with an eccentric body, the eccentric body is fitted into a fitting hole of an external gear to form a first contact surface, and the input shaft is disposed inside a fixed casing. A second contact surface is rotatably supported by the peripheral surface, and a third contact surface is formed by internally meshing the external gear with an internal gear portion formed on the inner peripheral surface of the fixed casing. A pin provided integrally with the output shaft is loosely fitted into the pin hole formed in the external gear, and a tip portion of the input shaft is loosely fitted into the hole formed in the output shaft so as to be freely rotatable. In the resin planetary gear speed increase/decrease device in which a fourth contact surface is formed in a resin planetary gear, a recess for retaining lubricant is formed in at least one of the first contact surface to the fourth contact surface. A resin planetary gear speed increase/decrease device characterized by:
