PROBLEM TO BE SOLVED: To smooth the open/close motion of the door of an elevator. SOLUTION: The door shoes 10a and 10b are mounted at two positions along a guide groove 14 of the door 12 of the elevator, and the two door shoes have shoe frames 16 to be fixed to the door and rollers 18a and 18b supported by both ends of each shoe frame. The rollers are disposed in such a way that the outer surfaces of the rollers project from the shoe frames outward in the door opening/closing direction and in the direction orthogonally crossing the door opening/closing direction. Because of the structure, the rollers 18 abut to side walls 30a and 30b of the guide groove 14 even if the moment to twist the door 12 is applied, and the friction of the opening/closing door is reduced and the motion of the door is smoothed.
