Claims

[Claims for Utility Model Registration] (1) A cylindrical back whose center is centered on the center of the support provided on the base, which brakes the rotation of the base that rotates around the center of the support. Within the circle of the plate, a piece having a plate of a predetermined width with sloped surfaces facing approximately in the radial direction of the circle at both ends is placed on the support so as to be placed at a position circumferentially away from the center of the circle. Two shoe members, which are fixed, have an arc equal to the arc of the back plate formed on the back surface, and one end of which is in contact with the slope of the end of the piece;
A control member whose back face faces the back plate, one end of which is in contact with the inclined surface of the end of the piece, and whose other ends are arranged to face each other, and which adjusts the spacing between the opposed ends. A swing braking device characterized by having a. (2) A device that brakes the rotation of the base that rotates around the center of the support body, and is a device that brakes the rotation of the base that rotates around the center of the support body, and is a device that A piece having sloped surfaces facing approximately in the radial direction of the circle at both ends of a board having a width of At the same time, attach two shoe members each having an arc equal to the arc of the back plate and one end of which is in contact with the slope of the end of the piece, with the back face facing the back plate, and one end of each shoe member. A swing braking device, characterized in that the control member is brought into contact with the sloped surface of the end of the piece, the other ends are arranged facing each other, and a control member is attached between the facing ends to adjust the interval between them. .
