Abstract
A two-speed transmission includes: an input member; an output member; a rotating member; a first engaging device switching engagement between first and second friction plates to switch the input member and the rotating member to an integrally rotating state or a relatively rotating state; a second engaging device switching the rotating member to a rotatable or non-rotatable state; an elastic biasing means applying a force pressing the first and second friction plates; a pressing device releasing the pressing force; a first bearing between the elastic biasing means and the pressing device; a second bearing between the rotating member and the pressing device or the fixed portion; and a planetary speed reduction mechanism having a sun element connected to the input member or the rotating member, a carrier connected to one of the input member or the rotating member and the output member, and a ring element connected to the other.
