Abstract
A manually movable wheeled storage rack or the like is disclosed which may be moved along a pair of rails when an operator rotates a handwheel attached to one side wall of the storage rack or the like. The storage rack or the like is further provided with a locking device so as to hold the storage rack or the like in a desired position and a safety device so that when a buffer plate of the safety device hits an operator or worker in the passage between the adjacent storage racks or the like as one of them starts to move by an accident, the safety device immediately locks the wheel, whereupon the operator or worker may be prevented from being sandwiched between the storage racks.
