Claims

[Scope of Claim for Utility Model Registration] (1) In a device that prevents an upper surface plate that moves up and down from falling, a support that moves up and down together with the upper surface plate, an overhang provided on this support, and this overhang. a support member that engages with and supports the support member; a holding member that holds the support member; and a drive device that is coupled to the support member and moves the support member to both engagement and disengagement positions with respect to the overhang. An upper surface plate drop prevention device for a polishing machine, characterized in that the support member is held by the holding member so that when the overhang hits the upper surface plate when rising, the support member is pushed away by the overhang. . (2) An upper surface plate drop prevention device for a polishing machine, characterized in that the support member is rotatably held on a holding member by a hinge and a spring, or a pin and a spring.
