PURPOSE:To absorb various kinds of errors such as a tooth profile error in a planetary gear mechanism, so as to achieve uniform loading of a transfer load, by respectively forming parallel guide collar parts into bushes. CONSTITUTION:Bushes 6 are fitted around both ends of a planetary gear shaft 4, and recessed grooves for radially float-and supporting the bushes are provided on the peripheries of carrier plates 8A, 8B, and parallel guide collar parts for floating the planetary gear shaft 4 parallel with the bushes 6 are formed on the bushes 6.
