PROBLEM TO BE SOLVED: To provide a power transmission device capable of being designed in various manners to meet various requirements such as increasing of transmission efficiency, reduction of noise and vibration or self-lock function while realizing miniaturization and space saving. SOLUTION: This power transmission arranged between an input shaft 302 and an output shaft 306 is comprised of a planet gear 100 meshed with an internal gear equipped with an externally toothed gear 102 and an internally toothed gear 104 with a slight difference in the number of tooth. A sliding portion between a plurality of inner pin holes 102a arranged on the externally toothed gear 102 and a plurality of inner pins 308 capable of transmitting rotational characteristics of the externally toothed gear 102 freely engaged with the pin hole 102a to the output shaft 306 are comprised of two kinds of first and second sliding portions. A transmitting portion of which transmission characteristics is made different from each other by giving a difference in sliding manners of the first and second sliding portions is parallely provided on a transmission passage, which forms the transmission 300.
