Differential moving device

Abstract

A differential moving device includes: an endless member constituting an endless path, the endless member including: a first path segment disposed inside; a second path segment disposed outside; and a connection path segment connecting the first path segment and the second path segment; a first driving roller engaged to the first path segment; a second driving roller engaged to the second path segment; a first driving motor that rotationally drives the first driving roller; a second driving motor that rotationally drives the second driving roller; a control unit that controls the first driving motor and the second driving motor; and a movable pulley unit including: a movable pulley that is engaged to the connection path segment and linearly moves along a first axial direction and/or rotates with movement of the first path segment and the second path segment; a first moving member that moves along the first axial direction with linear movement of the movable pulley; and a second moving member that is held by the first moving member and moves with rotation of the movable pulley.
