8, 40, and 42 are provided protrudingly. The projecting pieces 28, 3 are provided on one side of the upper and lower positions of the side plates 6, 8.
Fitting holes 44, 46, 48, 50, 5 at positions corresponding to 0, 32, 34, 36, 38, 40, 42
2, 54, 56, and 58 are provided transparently. Holes 60, 6 for roller arrangement are provided on the upper and lower sides of the side plates 6, 8.
2, 64, 66 are transparently provided, and the respective holes 60, 62,
There are pivot supports 68, 70, 7 on both sides of 64, 66.
2, 74, 76, 78, and 80, 82 are integrally provided in a protruding manner. Said pivot support 68, 72, 7
The holes 60, 62, 6, 80 have a locking wall surface formed at one end in a direction perpendicular to both sides of the side plates 6, 8, and the other end of the holes 60, 62,
A hole is formed in the side surface opposite to 64, 66, and the pivot support 70, 74, 7 corresponds to the hole.
Grooves 84 are formed in the side plates 8 and 82 in a direction perpendicular to both sides of the side plates 6 and 8. Each groove 84
are the fitting holes 44, 46, 48, 50, 52,
54, 56, and 58 are closely opposed to each other. The pivot support 68, 70, 72, 74, 76, 78, 80,
82 and the holes and grooves 84 formed therein constitute a shaft holding portion. 86 is a roller, 88 is a long spindle for the roller, and 90 is a short spindle.

Next, the operation of this embodiment will be explained.

To assemble the retainer from the state where the substrate 4 and the side plates 6, 8 are separated, first the roller support shaft 88 is slidably inserted into the shaft holding portion of the substrate 4. Next, the rollers 86 are arranged in the holes 20 and 24 of the substrate 4, and the rollers 86 are
Insert one side of the support shaft 88 into the shaft hole 6. Next, the rollers 86 are placed in the holes 22 and 26, and the other support shaft 88 is inserted into the shaft hole of the rollers 86. Next, the side plate 6,
The rollers 86 are arranged in the holes 60, 62, 64, 66 of No. 8, and in this state, the spindle 90 is inserted from the groove 84 into the shaft hole of the roller 86 and the closed hole at the end of each of the shaft supports 68, 72, 76, 80. insert. Next, the fitting holes 44, 46, 48, 50, 52, 54, 56, 5 of the side plates 6, 8
8 to the corresponding protrusions 28, 30,
36, 38, 32, 34, 40, 42. In this state, the overall combined cross-sectional shape of the substrate 4 and the side plates 6 and 8 forms a U-shape. In this coupled state, the surfaces of the side plates 6 and 8 on the opposite side from the shaft support mounting surfaces closely face both ends of the support shaft 88 on the board 4 side, and the side plates 6 and 8 act as stoppers to support the support shaft 88. Sliding movement along the longitudinal direction in the direction of coming out of the shaft holding portion is restricted. Further, each one end of the support shaft 90 on the side plates 6 and 8 is connected to the shaft support 68 and 7.
2, 76, 80, and the other end of the support shaft 90 is fixed to the locking surfaces of the holes 2, 76, 80,
32, 34, 40, and 42, and the movement of the support shaft 90 in the longitudinal direction is restricted by the projecting piece. As shown in FIGS. 5 and 6, the retainer assembled in a U-shape as described above is tightly fitted between the square cylindrical outer leg 92 and the inner leg 94. As is clear from FIGS. 5 and 6, the retainer body 2 consisting of the base plate 4 and the side plates 6, 8 is fitted into the three mutually perpendicular side wall surfaces of the internal leg body 94 via the rollers 86. , whose position is regulated by the side wall surface. Therefore, even if the inner legs 94 are moved up and down along the outer legs 92, the position of the retainer body does not shift in the lateral direction.
Furthermore, the pair of retainer bodies 2 facing each other are
Because they are separated, the legs 92, 94 shown in FIG. 5, which are wider than the standard dimensions, and the legs 92, 94 shown in FIG.
This can be applied if the distance between the opposing wall surfaces of No. 4 is the same. In this embodiment, the substrate 4 and the side plates 6, 8 are constructed separately, but they may be constructed integrally. Further, the rollers 86 are not limited to a cylindrical shape, and a spherical roller may be rotatably supported in a hole in the main body 2 or may be pivotally supported on the main body 2. The external legs 92 are erected on a base 96, as shown in FIG.
is installed. When the internal leg 94 is pressurized in the vertical direction, the internal leg 94 moves up and down along the wall surface of the external leg 92 due to the rotation of the rollers 86.
5 and 6 show that the retainer of the present invention can also be used between outer legs 92 and inner legs 94 of different dimensions. The above is an example in which the retainer of the present invention is used as an elevating guide part of an elevating drafting table, but it is not limited to an elevating drafting table, and as shown in FIG. It may be arranged between the outer leg 92 and the inner leg 94 of a medical instrument lifting platform to which a mounting plate 100 for storage or equipment is attached.

[Effect of idea]

As mentioned above, the present invention allows the roller to be easily attached to the board and side plate by simply inserting the spindle into the shaft support provided on the board and side plate.Furthermore, the roller can be easily attached to the board and side plate by inserting the protrusion into the fitting hole. When combined in a U-shape,
Both ends of the roller support shaft on the board side are locked by the side plate, and the end of the roller support shaft on the side plate side is locked by the protrusion on the board, so the roller support shaft moves in the axial direction. , there is an effect of being able to prevent the roller from coming off from the base plate and side plate.
