The invention relates to an advertising device in an elevator. The advertising device comprises an upper base plate (10), a lower base plate (20) and a shell (30), wherein the upper base plate (10) and the lower base plate (20) are connected through a bolt (104); a row of blocking slots (203) are respectively formed in the two sides of the lower base plate (20); the two ends of a rotating shaft b are blocked in the blocking slots (203); a row of positioning holes (204) are respectively formed in the two sides of the lower base plate (20); a moveable shell (301) sleeves the bottom of the shell (30). The advertising device in the elevator is simple in structure and convenient in use; the required height of the advertising board can be made by exchanging the blocked position of the rotating shaft b and exchanging the positioning hole positioned by the bolt, so that the device can adapt to the advertisements in different heights; the convenience in exchanging of the advertisements is realized; the advertising cost is saved.
