A locking apparatus of a game machine has the following components: a locking bar provided with a plurality of first engaging portions; engaging members having second engaging portions engageable with the first engaging portions; and a locking bar actuating member for actuating the locking bar from an engaging position where the first engaging portions engage with the second engaging portions to a disengaged position where the first engaging portions are out of engagement with the second engaging portions. A locking device performs, in accordance with operation of a key, a change-over between an unlocked state which permits the actuation of the locking bar into a disengaged position by the locking bar actuating member and a locked state which prohibits the actuation of the locking bar into the disengaged position by the locking bar actuating member. The locking bar is disposed on the main part, while the engaging members, locking bar actuating member and the locking device are disposed on the door hinged to the main part. This arrangement serves to reduce the size of the installation space to be preserved in the main part, while avoiding increase of the weight of the door assembly.
