Effects> In order to achieve the above object, the orthogonal module of the present invention surrounds a hollow frame member having a predetermined cross-sectional shape with a slide base portion and press-fits it to the outer circumferential surface of the frame member. By providing a plurality of roller members for positioning the member and applying rotational force to at least one roller member from a rotational drive source, the slide base member can be slid to a desired position. In addition, while integrally forming the frame member,
By appropriately setting the cross-sectional shape, the rigidity of the frame member can be made sufficiently high and the weight can be reduced. Furthermore, since the rigidity can be increased, the positioning accuracy of the slide base member can also be increased. Furthermore, since the overall number of parts can be reduced, assembly and adjustment are significantly easier, and the relative positioning of the frame member and slide base member can be achieved by press-contacting multiple roller members, making positioning work easier. It can also be simplified,
Furthermore, positioning accuracy can be increased.

To explain in more detail, the frame member (1) is made of, for example, alloy steel with excellent surface treatment properties. The pair of roller members (3a) is, for example, a frame member (1
) is supported by the slide base member (2) by a bearing (3d) so as to be in pressure contact with the upper surface of the roller part H (3a), and the roller shaft of the - side roller part H (3a) is connected to the rotational drive source ( 4) is connected. However, both roller members (
3a) may be connected to a rotational drive source (4). The other pairs of roller members (3b) and (3c) are moved by shafts (3e) to the slide base member (
2), and each pair of roller members (
By pressing 3a), 3b, and 3c onto the frame member (1), the relative position between the frame member (1) and the slide base member (2) can be set accurately. Note that the force required to move the slide base member (2) is
This can be obtained by adjusting the load applied between Specifically, the corresponding roller members (3a) (3b)
A desired load can be easily obtained by adjusting the distance between the rollers (3c), interposing an elastic body as appropriate, or replacing the rollers (3b) and (3c) with ones having different outer diameters. Further, although a frame member (1) having an octagonal cross section is used, it is possible to use a frame member having an appropriate cross section such as a hexagonal cross section.

If the orthogonal module has the above configuration, the rotary drive source (4
), it is sufficient to simply rotate the roller member (3a),
Since the frame member (1) is pressed by the roller members (3a), (3b, and 3c), a frictional driving force acts, and the predetermined position is determined based on the rotational direction and rotation amount of the rotational drive source (4). The slide base member (2) can be moved up to. When the rotational drive source (4) is not operated, the slide base member (2) can be stopped at a desired position.

<Embodiment 2> Fig. 3 is a longitudinal sectional view showing an embodiment in which an orthogonal module is used as the vertical axis, and the differences from the above embodiment are as follows.
A boob 9 (5) is provided near the upper end of the frame member (1), and a slidable piston member (6) is provided that engages in an airtight manner inside the frame member (1), and both are connected by a wire (force). The only points are the connection point and the provision of a pressure fluid source (9) that supplies pressure fluid through a cover member (8) covering the upper end surface of the frame member (1).

Therefore, in the case of this embodiment, the rotational drive source (4) is used to slide the slide base member (2) upward.
When operating the frame member (1), it is sufficient to supply pressure fluid to the inside of the frame member (1) from the pressure fluid source (9) via the wire (7) wound around the piston member (6) and the pulley (5). Since an upward force is applied to the slide base member (2) by the movement, not only can the load on the co-rotating drive source (4) be significantly reduced, but also the roller member (3a) (
3b) It is also possible to significantly reduce the increase in the pressure contact force between (3c) and the frame member (1). Furthermore, since there is no need to provide a balance weight externally and it is sufficient to provide the piston member (6) inside the frame member (1), it is possible to significantly suppress the increase in size of the orthogonal module as a whole.
