PROBLEM TO BE SOLVED: To provide an epicyclic gear to be assembled without risk of misassembling when a thrust washer having obverse and reverse surfaces is installed. SOLUTION: The epicyclic gear 5 has a planet carrier 13 where the thrust washer 54 in a ring shape is installed between a ring gear 14 and the periphery of the planet carrier 13 in their axial direction. The thrust washer 54 has three pairs of washer side pawls 54a protruding inward in such a way as pinching three columnar parts 51c formed on the planet carrier 13 in their rotating direction and washer side recesses 54b to be concave toward the periphery in such a way as to comply with the shape of the addendum in the neighbourhood of the inside surface of the thrust washer 54 of a second pinion 62. By the washer side pawls 54a the thrust washer 54 is engaged with the planet carrier 13 in such a way as to be incapable of rotating. The axes P1 and P2 of the pinions 61 and 62 are located in eccentricity in the rotating direction from the center line O-D between the columnar parts 51c.
