Abstract
Abstract Disclosed is a lid lock structure for a hinged lid of a recess which is made in a car body to conceal a fueling port. The lid lock structure includes a latch housing containing a bolt and having a plate spring at its head. The bolt catches a catch leg extending from the back of the hinged lid when closed, whereas the plate spring is yieldingly bent to constantly apply pressure to the lid while it is closed. When the bolt is retracted, the lid is unlatched to snap open. The built-in spring structure facilitates assembly work.
