PROBLEM TO BE SOLVED: To provide a door pickproof mechanism capable of preventing a door portion from being easily broken open even if a sheet metal portion is deformed by a strong break-open force applied thereto. SOLUTION: When the break-open force is applied to the door portion by inserting a bar 13 in a clearance between the depth part 12b of a door 12 and the depth part 11b of a casing 11, even if the door 12 is deformed by the break-open force, the engagement projected part 12d of the door is engaged with the inside of the slit 11e of the casing 11. Accordingly, since the engagement projected part 12d is engaged with the slit 11e even if the break-open force is further applied thereto, the door portion is hard to be deformed and a suppressing force against picking can be increased.
