DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings.

(Embodiment 1) In Embodiment 1, a railway model generally called an N gauge will be described as an example. FIG.
FIG. 2 is an exploded perspective view of a cleaning head and a traveling wheel of the railroad model rail cleaning device according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view of the cleaning head of the railroad model rail cleaning device.

As shown in the figure, a railroad model rail cleaning device 10 includes a locking member 20 incorporated in a vehicle,
The cleaning head 30 includes a cleaning head 30 that engages with the locking member 20 during cleaning traveling to clean the rail, and a traveling wheel 70 that engages with the locking member 20 during traveling to assist the vehicle in traveling.

The locking member 20 has a fixing portion 23 made of a plate-like member. The fixing portion 23 has a pair of opposing side surfaces having fixing protrusions 21 for engaging with the bottom of the vehicle. It has a rectangular through hole 22 at substantially the center. One end of a rectangular cylindrical holding portion 25 having an engaging portion insertion hole 24 is fitted and fixed to the through hole 22 of the fixing portion 23. The fixing of the holding portion 25 to the through hole 22 is not particularly limited, such as bonding with an adhesive or fixing by press-fitting.

On one side surface of the holding portion 25 of the locking member 20, there is provided a long hole 26 which is a through hole which is long in the insertion direction of the engagement portion insertion hole 24. A locking hole 27 that is a through hole is formed.
