Abstract: A unit connecting mechanism and box-like unit is disclosed having an engaging unit (4) and a connecting pin (3) which are mounted to the box-like unit (1) to allow a plurality of box-like units (1,1) to be coupled to one another in a vertical direction. A handle (44) is operatively connected to a hook (43) to catch an engaging rod (3a) and is vertically raised to cause a stopper (45) to lock the hook (43) and the engaging rod (3a) in a locked condition, with operation of the handle (44) causing the stopper (45) to move downward to cause the hook disengage from the engaging rod for thereby uncoupling the box-like units (1,1) from one another. As a result, the unit connecting mechanism can be manufactured in a compact structure, providing a capability for a worker to easily and appropriately perform coupling and uncoupling operations of the box-like units.
