1. A hydrogen production apparatus comprising: a water electrolysis unit that electrolyzes water to generate hydrogen gas; a storage unit that stores the hydrogen gas generated in the water electrolysis unit; a supply unit that supplies the hydrogen gas stored in the storage unit, to outside; an electrical unit that controls operation of at least the water electrolysis unit; and a housing that houses the water electrolysis unit, the storage unit, the supply unit, and the electrical unit,
wherein:
the housing comprises at least an upper frame disposed on an upper side of the housing in a height direction thereof and a lower frame disposed on a lower side thereof in the height direction, and includes an opening end opened in a lateral direction orthogonal to the height direction; and
the housing further includes:
an opening/closing door rotatably supported on the housing and configured to open and close the opening end; and
a locking mechanism disposed on the opening/closing door and configured to restrict an opening operation of the opening/closing door with the opening end being closed; and
wherein:
the locking mechanism includes first and second rods configured to move along a height direction of the opening/closing door orthogonal to an opening direction of the opening end;
in an opening operation restricted state in which the opening end is closed by the opening/closing door and the opening operation of the opening/closing door is restricted by the locking mechanism, an upper end of the first rod is disposed on an opposite side of the upper frame from the opening/closing door, and a lower end of the second rod is disposed on an opposite side of the lower frame from the opening/closing door;
in the opening operation restricted state, a first enlarged diameter portion formed in a vicinity of the upper end of the first rod and enlarged in diameter radially outwardly is in a state of being inserted into a first guide portion disposed on the opening/closing door and extending in a direction opposite to the opening direction of the opening end, and a second enlarged diameter portion formed in a vicinity of the lower end of the second rod and enlarged in diameter radially outwardly is in a state of being inserted into a second guide portion disposed on the opening/closing door and extending in the direction opposite to the opening direction of the opening end; and
an axial distance between an upper end of the second enlarged diameter portion and the second guide portion is larger than an axial distance between a lower end of the first enlarged diameter portion and the first guide portion.
