In the conventional elevator door rail cleaning device, the cleaning brush body is made of an elastic felt-like material because of its role as an oil supply device (for example, Patent Document 1 and Patent Document 2, paragraph number 0020).

On the other hand, elevator door rails often have a convex upper portion in a cross section viewed from the longitudinal direction of the door rail. This is a door hanger provided on the upper end side of the door and a hanger roller provided on the door hanger and rolling on the door rail along the longitudinal direction of the door rail, and the hanger roller does not come off from the door rail. As described above, the surface of the hanger roller that comes into contact with the door rail is concave, and the convex portion at the top of the door rail is fitted into the concave portion of the hanger roller.

By the way, with the use of an elevator, dust or dirt with viscosity in which dust and oil are mixed adheres to the door rail. In order to remove these dusts and the like, the cleaning brush body having higher hardness is more effective for scraping off the dusts and the like. However, when it has a function as an oil supply device, it is necessary to impregnate oil, and it is necessary to use a felt-like material such as a felt-like material as in Patent Document 1 or Patent Document 2.

As described above, when the material of the cleaning brush body is made of a felt-like material such as a felt-like material, the cleaning brush body is aligned with the convex portion of the upper portion of the door rail when the cleaning brush body is pressed against the door rail. The body is deformed, and the upper part of the door rail can be evenly cleaned or refueled.

However, when the material of the cleaning brush body has a high hardness in order to more strongly remove dust on the door rail or dirt with viscosity in which dust and oil are mixed, there are the following problems. The problem will be described with reference to FIG.
