The trap door is hinged on a part (16) both having hinge knuckles (26,28) forming an eyelet for the passage of a hinge rod (20). One of the knuckles has a radial slot (42)which enables the engagement of a reduced section (40) of the rod in the slit knuckle in a radial direction. The hinge has a reduced number of components enabling good rotational guidance. Drawings show the hinge rod and its mounting in the knuckles. |
