Abstract

A knee joint that is capable of widening a moveable range, and that has good energy efficiency and is small and lightweight is described. Also described is a knee joint that is of an active type, but comparatively inexpensive. A drive section moves a driven member. An elastic member is arranged between the driven member and a linear motion member. The linear motion member elastically moves in at least one direction, in accordance with movement of the driven member, by way of the elastic member. A crank mechanism can realize bending and extension of the knee joint by converting linear motion of the linear motion member to rotational motion.
