Abstract
Guide tracksprojecting in a vertical direction are provided in a right and left of a running trackand left and right guide rollersare provided on a track guided vehicle and guided using inner surfaces of the left and right guide tracks. Branching rollerseach comprising elevating and lowering means are provided in the right and left of the track guided vehicle and outside the right and left guide tracks. Thus, branching and rectilinear progression of the track guided vehicle is controlled by switching between a state where the branching rollersare elevated or lowered to guide the track guided vehicle using outer surfaces of the guide tracksand a state where the branching rollersdo not contact with the outer surfaces. Whether the track guided vehicle runs straight or shifts to a branch line can be controlled by contacting one of the branching rollerswith the outer surface of the corresponding guide tracks, which guide the guide rollersin the section (rectilinear progression section) different from the branching portion
