摘要:
An improved planetary gear type transmission mechanism is provided which is capable of realizing a plurality of desired speed ratios in a wide range, for example in an automatic transmission, and which maintains gear ratios of all of a plurality of planetary gear sets in an available range. The transmission mechanism includes a double pinion type planetary gear set.
