SHOWA IZ, inspection and repair due to malfunction of the entrance door

"Inspection and repair of door operation malfunction"

Since the door sometimes does not close, I would like to ask for an inspection.It is said that the door will open so that it can slip out.

I thought that the position of the latch bolt and the strike was wrong, but when I checked the actual product, the strike was attached diagonally.

It looks like it has been in use for over 20 years.Judging from the rust condition of the parts, it may have passed more.The apartment itself is 38 years old.

The cause is that the gap has opened wide due to the big distortion of the door frame.It is a symptom that the latch bolt does not reach the strike.

I adjusted it so that half of the latch bolt is caught by using a spacer etc.
