梁１０とで逆Ｕ字形をなす門形移動体を構成している。In the figure, reference numeral 10 indicates a beam related to a beam body constituting a moving body. Reference numeral 11 is a ball screw connected to a motor 13 via a coupling 12 to constitute a driving means. Reference numeral 14 indicates a threaded portion of the beam 10 where the ball screw 11 is engaged. 15.1
Reference numeral 6 denotes slide units related to guide means on both sides of the beam 100, and these slide units 15, 16 and the beam 10 constitute a portal-shaped moving body forming an inverted U shape.

る。The position of the guide means relative to the drive means is asymmetrical. In the example shown in FIG. 3, the distance m between the slide unit 15 and the ball screw threaded portion 14 is greater than the distance n between the slide unit 16 and the ball screw threaded portion 14. Slide unit 15 on the side with a larger distance from the ball screw threaded part 14
A plate spring 17 is interposed at the joint between the beam 10 and the beam 10.

な直線運動が確保できる。When the motor 13 is driven and the ball screw rotates, the driving force is transmitted to the vermilion 10, and when the 9i1.10 moves or accelerates or decelerates, the beam 10 is not a completely rigid body, so it bends, and a moment is generated on the slide unit 15 side. join. In this example, a plate 1 is installed at the joint between the beam 10 and the slide unit 15.
7, it is possible to reduce the above-mentioned moment applied to the slide unit 15 or the rail 21, maintain the rigidity of the slide unit 15 against loads perpendicular to the plane of the paper, and improve the smoothness of the portal moving device. Precise linear motion can be ensured.

ーメントの低減を十分所期しうるものである。In this embodiment, the beam 10 and the slide unit 15 are connected by interposing the leaf spring 17 only on the side of the slide unit 15, but it is not necessarily limited to only one side. For example, as the position of the ball screw threaded portion 14 changes and the degree of man changes, leaf springs may be interposed on both sides of the slide unit 15, 16 to create a difference in the spring strength of the leaf springs on both sides. , it is possible to fully achieve the purpose of the present invention, which is to reduce the moment.
