To provide a suspension holder for easily keeping a balance at any position when a radio graphic apparatus moves up and down along a supporter.
A movement frame 10 linked with a radiographic instrument holding frame 3 via a wire 6, a first fixed pulley 5, a second fixed pulley 7, and a movable pulley 8 moves linearly up and down along a guide rail G2 provided in the prop 2, and a roller 14 at the tip of rotary levers 13A and 13B hanging a projection surface 11 of a lower end of the movement frame 10 is lifted up, so that weights of the radiographic instrument 4 and the radiographic instrument holding frame 3 become fixed rotational force in accordance with rotation angles of the rotary levers 13A and 13B. On the other hand, since a compression coil spring 17 pulls the rotation levers 13A and 13B via a chain 15 and sprockets B, C, and D, restoration force of the compression coil sprint 17 becomes a fixed rotational force in accordance with rotation angles of the rotation levers 13A and 13B. As a result, when the radiographic instrument 4 moves up and down along the prop 2, it easily keeps a balance at any poisition.
