Jared Fogle's brass balls are rattling -- the child porn convict is actually suing the parents of one of his victims, blaming them for the teen's problems.

Fogle's suit targets the parents of a "Jane Doe" ... who earlier this year sued him and his ex-employee, Russell Taylor. In his lawsuit, obtained by TMZ, Fogle says the girl's parents screwed her up when they got divorced.

He says they frequently fought and abused alcohol in front of "Jane Doe," which caused her to suffer major depression and engage in "destructive behaviors" -- including abuse of drugs and alcohol, self-mutilation and having suicidal thoughts.

You should recall, the victim says Fogle and Taylor shared nude videos and pics of her.

Fogle -- who's doing just over 15 and a half years in prison -- is trying to say the girl's parents should be partially or fully responsible for all the claims she's making against him.
