LOCKING DEVICE FOR MOVABLE STORAGE RACK ABSTRACT A locking device for a manually movable wheeled storage rack is disclosed, which storage rack is provided with a manually operated rotatable handwheel, and power transmission mechanism for transmitting the rotational power imparted to the rotatable handwheel to drive wheels, thus causing the storage rack to be moved. The locking device is movable forward and backward in the axial direction thereof by manual operation at the rotatable center section of the rotatable handwheel. This locking device is capable of restricting the action of the power transmission mechanism, rendering the transmission of the motive force im- possible, thus making the storage rack incapable of motion. This device can subsequently be released, thus rendering the movable rack once again capable of motion. The rotatable handwheel is equipped with a drive shaft which can be made to move in the axial direction thereof by means of operation in that direction, and this drive shaft, by movement in the axial direction thereof, causes the locking device to be moved, rendering the operation of the power transmission mechanism impossible by means of restrictive action, and can subsequently be released, making operation once again possible.
