ABSTRACT:
According to the invention a door latch includes a cylindrical plastic housing member adapted for mounting within an aperture of a vehicle door and having an integrally molded escutcheon which overlies the walls of the door panel defining the door aperture. A molded plastic cylindrical handle member is rotatably journaled within the housing for rotary movement. A plastic cylindrical actuator member rotatably journaled within the handle member is connected with the door latch to unlatch the door latch upon axial movement of the actuator member. A cam means acts between the handle member and the actuator to effect axial movement of the actuator member in response to rotary movement of the handle member. The housing member preferably has upper and lower walls having coaxially lined apertures, while the handle member and a guide member slidably carried by the handle member each have integral bosses adapted to slip fit within the apertures of the walls of the housing member. A spring acts between the housing member and the guide member urging axially apart movement so that the bosses are retained in engagement of the coaxially aligned apertures to journal the handle member on the housing for rotary movement.
