Ｃは転倒する。[Detailed Description of the Invention] A movable shelf equipped with wheels at the bottom at a predetermined distance from front to back so as to be able to reciprocate in a direction perpendicular to the opening surface is, for example, as shown in FIG. , when the bottom of the movable shelf C collides with the stopper b protruding adjacent to the rail a, the horizontal force F due to inertia or an earthquake is applied to the center of gravity G of the movable shelf C (from the rail a to the shelf center of gravity G). When the height of h) acts on the movable shelf C, an overturning moment of F-h occurs on the movable shelf C, but this overturning moment) F-h is the upright moment) W-X (W is the shelf weight and X is the shelf weight) If the distance between the perpendicular line drawn from the center of gravity G to the rail a and the wheel center is exceeded, the movable shelf C will overturn.

用的でない）ため、車輪間隔２Ｘはｙ−２ｒ（ｒは車輪
ｄの半径）を越えることができない。Therefore, in order to improve the stability of the movable shelf C, it is obvious that the distance 2X between the wheels d should be made as large as possible compared to the height h of the center of gravity. Although the extent to which this can be achieved is reduced by arranging it at the bottom of the shelf, there is a limit depending on how the user uses it, and the depth y of the movable shelf C is also limited in terms of storage efficiency. Due to its nature, it is not possible to position the wheel d outward from the shelf front surface (it is not impossible, but the structure is extremely complicated and impractical from a cost standpoint), so the wheel spacing 2X is y-2r. (r is the radius of wheel d).
これを具体的に１例について説明すると、片側の間口面

倒する惧れは充分にあった。To explain this in detail with one example, in a normal bookshelf type movable shelf C where books are put in and taken out from the frontage of one side,
The depth y is about 30 cm, and the wheel radius is 5 cm considering the load, running resistance, etc., so the wheel spacing is 2.
X is 20 cm, and the height of the center of gravity of movable shelf C is approximately 100 cm.
cm, and therefore, there was a strong possibility that the horizontal force F would exceed 115 of the shelf weight W of the movable shelf C and the movable shelf C would topple over when the wheels were fixed.

隙は成る値以上広くなることが避けられながった。In order to prevent this, conventionally, as shown in FIG. The stopper e moves along the rail a as the movable shelf C travels, and since the dimensions of the rail head are not constant over the entire length of the rail, It was inevitable that the gap between the piece e and the upper surface of the protrusion would become wider than the required value.

れる。As a result, when the overturning moment (F-h) due to the horizontal force F exceeds the upright moment (W-X), the movable shelf C tilts until the locking piece e engages with the head of the rail a. The distance X between the perpendicular line drawn from the center of gravity G to the rail a and the wheel center decreases, and if this is X and the downward engagement resistance force of the locking piece e is P, then the upright moment w-x' and the resistance moment P -X', the fall prevention moment) M is M=W -X'+P -X'=(W0P)・X', which is larger to the left than the upright moment W-X in the upright state. Therefore, the effect of providing the locking piece e is diminished.
