The engaging portion 121 of the rail 120 is formed to have a concave portion corresponding to the engaging portion 111 of the slider 110 or a convex portion or concavo-convex portion .

The rail 120 has a locking groove 122 formed on a side surface thereof to receive and accommodate the locking protrusion 134 of the locking means 130.

A plurality of locking grooves 122 are formed at regular intervals in the longitudinal direction of the rails 120 according to the number of seatings 100 installed.

Accordingly, the number and spacing of the sheet member 140 coupled to the upper surface of the slider 110 can be variously adjusted.

That is, in order to widen the interval of the seat 100 of the train, the slider 110 is installed by skipping over one or more intervals of the lock grooves 122 formed to lock or unlock the movement of the slider 110, In order to form a conventional seat arrangement, the slider 110 is positioned and fixed for each lock groove 122.

When an event (event) of a sightseeing train is required, the entire slider 110 is moved toward one end of the rail 120 regardless of the lock groove 122, so that the slider 110 is closely contacted with each other. Thus, the space required by the user can be easily secured.

The locking means 130 locks or unlocks the slider 110 fixedly or movably coupled to the slider 110 through the rail 120 and coupled to the sheet member 140.

To this end, the locking means 130 includes a first rotation shaft 131 having a first gear 131a and a second rotation shaft 131, which are positioned laterally (horizontally) through the slider 110, A second rotation shaft 132 having a second gear 132a coupled to the second rotation shaft 132 and configured to be positioned vertically (vertically), and a second rotation shaft 132 coupled to a lower end of the second rotation shaft 132, And a cam 133 which is formed integrally with the center of both sides of the rotating body 133 so as to move inward and outward while being coupled with the lock groove 122 of the rail 120, A lock protrusion 134 for fixing or releasing the slider 110 when the slider 110 is detached or separated from the inner surface of the slider 110, And an elastic body 135 elastically supporting the locking protrusion 134.
