- a plurality of balls 15 are positioned between the movable member 13 and the intermediate member 14, the intermediate member 14, and the fixing member 17, so that the intermediate member 14 is fixed by rolling along the track.
- the moving member 13 slides along the intermediate member 14 so that the slide 10 is operated in three stages as a whole.
- the sliding device 10 of the prior art of US Patent No. 6,132, 020 is arranged up and down in the direction in which the three rows of raceways face each other so as to withstand the load.
- the moving member 13 is open at the side and bottom of the drawer plate 11 in the center direction.
- the moving member 13 is provided with a track part at the upper part of the center direction of the drawer board 11, and the upper and lower edges of the desk board 16, respectively.
- the side and the top of the fixing member 17 in the direction of the desk board 16 are open.
- the fixing member 17 has track portions formed at the lower edges in the direction of the desk plate 16 and in the upper and lower corners in the center direction of the drawer plate 11.
- the intermediate member 14 is formed with track portions at corresponding positions such that the intermediate member 14 is in rolling contact with the ball in rolling contact with the track formed on the movable member and the fixed member.
- the prior art sliding device 10 carries the load generated by the weight of the drawer plate 11 and the weight of the drawer internals in the direction of the desk plate 16 of the movable member 13 shown on the cross section of the sliding device 10.

- the fixing member 17 together with the intermediate member 14 while the ball 15 provided up and down in the direction of the drawer plate 11 and the ball 15 provided below the desk plate 16 form a substantially triangular shape. I support it. Therefore, the ball 15 is formed on the upper part of the intermediate member 14 in a triangular shape with the vertex in the direction of the desk plate 16.
- the ball 15 is formed in a triangular shape at the position facing the ball 15 on the top with the vertex in the center direction of the drawer plate 11. That is, the conventional sliding device 10 can withstand the load generated in the downward direction at both ends of the drawer plate 11 by arranging the balls 15 to face each other in the lower direction at both ends of the drawer plate 11. Has a structure.
- the conventional sliding device is provided with six rows of tracks up and down, and the moving member, the fixing member, and the intermediate member have a structure in which they slide in contact with the ball and slide. Accordingly, the sliding device has to maintain the structure of the rolling contact by the six rows of tracks and the ball installed therein, it is difficult to reduce the volume of the device.
- the sliding device of the prior art has to produce an intermediate member having a track portion on which six rows of tracks are provided, which makes the shape of the intermediate member bent by plural times to produce a plate.
- the intermediate member of such a complicated shape becomes a factor which increases manufacturing cost.
- the load by the weight of the drawer and the weight of the inside of the drawer is concentrated under the drawer withdrawal direction.
- the load concentrated in the withdrawal direction of the drawer acts as a torsional load on the sliding device fixed to both sides of the drawer. That is, when the load is concentrated in the draw direction of the drawer, the torsional load is generated in the sliding device located on both sides toward the center of the drawer.
- the sliding device of the prior art is provided with six rows of raceways facing each other to withstand the load generated in the drawer plate direction on the movable member on which the drawer is installed and the fixed member fixed to the desk plate. The resistance to withstand the torsional load acting in the center direction is greatly reduced.
- the six rows of tracks and the balls installed therein are vulnerable to torsional loads because they have a structure to withstand the load from both sides of the drawer in the downward direction.
- the six rows of tracks arranged to withstand the load acting downwards at both ends of the drawer and the balls installed therein are less resistant to torsional loads acting in the center of the drawer.
- a downward load downward occurs at one end in the withdrawal direction and an upward load upward in the other end at the opposite end in the withdrawal direction.
- the loads generated in the up and down directions are equally distributed when the number of tracks is a power of two. That is, the sliding device must be provided with a track that can uniformly distribute the load of the up and down in the quantity of the power of 2 between the intermediate member and each member that is in contact with the cloud up and down.
