Is my electrical junction box suitable to hold a ceiling fan


I recently bought a house and there are no ceiling fans in any of the rooms. I am trying to install a fan but read about junction boxes that a fan rated box is necessary. The house was built in 1957 and the box does not state anything about the rating.

Below are the pictures of the box. Please check and let me know if it can hold a ceiling fan of about 22lbs or do I need to go ahead and replace the boxes to install the fans?

The key would be where the screws that hold the fan bracket attach themselves. If they run through those holes and are attached via a threading on the back of the box, and they are 10-24 thread screws, then, yes, it is fan rated. If the screws just screw into the flange, then you must change the box to a fan rated one.
