摘要： PURPOSE:To enable running of a transport vehicle safely on an acutely curved track with less running resistance by arranging a centering truck and guide wheels at a base frame. CONSTITUTION:There are provided centering trucks 15 directing oppositely toward front and rear end directions at the lower front and rear portions of a base frame 2 for supporting total load of carried freight 1, and a guide mechanism including a guide axle 16 and guide wheels 17 underneath the base frame 2 so that the wheels 17 are slidably brought into contact with the inside surface of tracks 7. Thus, the wheels 12 of the trucks 15 direct tangentially regardless of the amplitude of the curvature radius of the track 7, and the wheels 17 guides and holds the base frame 2 horizontally and in the direction perpendicular to the traveling direction for enabling running of the vehicle safely and smoothyl on an acuteyl curved track.
