Abstract

PURPOSE: To reduce noise and increase the efficiency of the transmission by clamping each of elastic bodies between one of a pair of thrust bearings fitted in the inner peripheral surfaces at both ends of a plurality of planetary gears and one of supporting members.
CONSTITUTION: Three circular depressions 11e are formed at the peripheral edges of the inner end opening parts of three through holes of a supporting member 11b, and an elastic body consisting of three counter-sunk springs is fitted in one of the small-diameter parts 14a of three double-screw bolts 14 and clamped between three thrust bearings 31 and three circular depressions 11e. When a nut 16 is screwed in the male screw part 14b of the double screw bolt 14 and rotated in the clamping direction, the elastic force is gradually increased, and a pair of the thrust bearings 30 and 31 are urged against the planetary gears.
