Claims

[Claims for Utility Model Registration] 1. A ball screw rotatably supported by fixed bearings at both ends and driven to rotate; In a wave-making device comprising a ball nut that reciprocates due to rotation of a ball screw, and a wave-making plate fixed to the ball nut and suspended in a water tank, the guide is provided on both sides of the ball nut in the longitudinal direction of the ball screw. A wave-making device characterized in that a pair of intermediate movable bearings that engage with a rail are slidably mounted, and a connecting rod is provided that connects each intermediate movable bearing at a predetermined interval. 2. The wave-making device according to claim 1, wherein each intermediate movable bearing contacts a ball nut and then moves with the reciprocating movement of the ball nut. 3. The wave-making device according to claim 1 or 2, wherein the connecting rod has a length such that when one intermediate movable bearing is brought close to one fixed bearing, the other intermediate movable bearing is positioned approximately at the center of the ball screw. Device.
