         8 . The food-holding tray according to  claim 4 , wherein said rear end section of said guide rail has a ceiling surface and an upwardly raised contact plateau disposed on said ceiling surface, said contact plateau and said recess overlapping one another in the depth direction of the food-holding tray. 
     
     
         9 . The food-holding tray according to  claim 1 , wherein said tapered end section of said guide rail has a front end with a height and a rear end with a height, and said height of said rear end is between 40% and 60% of said height of said front end. 
     
     
         10 . The food-holding tray according to  claim 1 , wherein:
 said tapered end section of said guide rail has a front end;   said guide rail has a delimiting wall at which said front end of said end section ends; and   said delimiting wall is a stop wall for a stop of the at least one tray-external guiding apparatus.   
     
     
         11 . The food-holding tray according to  claim 10 , wherein the stop is a push-in stop of the at least one tray-external guiding apparatus. 
     
     
         12 . The food-holding tray according to  claim 10 , wherein said stop wall is an integral part of a framework structure of said guide rail. 
     
     
         13 . The food-holding tray according to  claim 1 , wherein said side wall has a convexly bulging lower region, and said guide rail is disposed on said convexly bulging lower region. 
     
     
         14 . The food-holding tray according to  claim 13 , wherein an entire height of said guide rail is within said convexly bulging lower region. 
     
     
         15 . A guiding apparatus for guiding a food-holding tray of a household refrigeration appliance according to  claim 1 , the guiding apparatus comprising:
 a guide channel for receiving and guiding said guide rail disposed on said external side of said side wall of said food-holding tray;   said guide channel having a ceiling surface and a floor surface; and   said guide channel having at least one of a push-in stop for said guide rail disposed in said guide channel or a pull-out stop for said guide rail disposed outside of said guide channel.   
     
     
         16 . The guiding apparatus according to  claim 15 , wherein said ceiling surface is a ceiling surface of a ceiling wall of said guide channel, and said floor surface is a floor surface of a floor wall of said guide channel. 
     
     
         17 . The guiding apparatus according to  claim 16 , wherein said ceiling surface has a downwardly projecting contact plateau disposed on said ceiling surface. 
     
     
         18 . The guiding apparatus according to  claim 17 , wherein said contact plateau is provided in a front third of a length of said ceiling surface. 
     
     
         19 . A household refrigeration appliance, comprising a food-holding tray according to  claim 1 . 
     
     
         20 . The household refrigeration appliance according to  claim 19 , which further comprises:
