PROBLEM TO BE SOLVED: To provide a mobile rack facility allowing any vehicle in a passage for works to run through in one direction, in which a bunch of mobile racks can run in the right angle attitude with respect to the running path. SOLUTION: Pulse encoders 21 are coupled with a motor 16 of a drive type running support device positioned on both sides in the width direction of a mobile rack running path (crawler), and a mobile rack controller 41 controls the driving rotation amount of the motor 16 on the basis of the pulse signals given by the pulse encoders 21. The controller 41 determines the running distance of each drive type running support device by counting the pulses emitted from the encoders 21, and if any difference is generated between the numbers of pulses, a mobile rack deviation (inclination) correcting control is conducted whereby the presumed running distance of each drive type running support device after a certain time is determined from the running distance and the speeds (driving rotation amount) of the motors 16 are controlled so that the deviation between the presumed running distances nullifies.
