Abstract
In a walking assist device having leg links each connected to a support member through a first joint and having a first link and second link connected to the first link through a second joint, and actuators to be operated to displace the first and second links relative to each other to produce assist forces that assist part of user's body weight to assist the user to walk, it is configured such that a forward protruding amount of the second joint to be protruded with change of an angle between the first and second links about the second joint is changed. With this, it becomes possible to decrease the forward protruding amount to be protruded from the trunk of the user with change of the angle about the second joint, thereby decreasing the inertia force about the vertical axis, while mitigating the unnatural impression of the appearance.
