車装置の背隙調整機構。 A carrier rotatably supporting the planetary gear is configured by mutually fastening a first carrier located on one side in the axial direction of the transmission and a second carrier located on the other side, The first of these
and a planetary gear device in which a sun gear and the planetary gear are arranged between a second carrier,
The first and second carriers are fastened to each other by fastening bolts installed in a plurality of bolt fastening holes formed therein, and at least one bolt among the plurality of bolt fastening holes is fastened to each other. In the fastening hole, a fastening hole portion formed on the first carrier side and a fastening hole portion formed on the second carrier side are formed at eccentric positions, and these fastening holes One side of the part and the fastening bolts passed through these fastening holes each include:
A planetary planet characterized in that a tapered surface is formed that can generate a pressing force that moves the fastening hole portions in a direction to eliminate the eccentricity of the fastening hole portions by the screwing force of the fastening bolt. Gear device back gap adjustment mechanism.
