Abstract

PURPOSE:To make an extremely low speed step settable anew as well as to make such fifth speediness that makes a gear ratio range between the minimum speed step and the maximum speed step larger than that of a four-speed type gear shifter performable by making the gear shifter of an automatic transmission into the fifth speediness through a series connection between a four-speed type main planetary gear shift mechanism and a two-speed type planetary gear shift mechanism. CONSTITUTION:When a forward clutch F/C is operated, a ring gear 6R is checked of its reversion by a forward one-way clutch F/OWC, and power from an input shaft 1 to a sun gear 6s rotates a carrier 6c in the same direction as the input shaft 1 after being decelerated. Here, when a sun gear 7s is clamped by actuation of a reduction brake RD/B, rotational power of the carrier 6c further decelerates an output shaft 2 in accordance with a carrier 7c and makes it rotate in the same direction, thus a first gear speed step of extremely low speed is secured. And, when a high clutch H/C and a band brake B/B are operated in an operating state of a direct clutch D/C, the turning force reached to a carrier 5c from the input shaft 1 is transmitted to the carrier 6c after being speeded up so that a fifth gear speed is secured.
