Abstract
A rotating gantry includes a link frame for supporting a plurality of rollers which rotatably support the rotating gantry, a brake for releasing a braking force applied to at least one of the rollers upon supply of air and applying the braking force to the one roller upon discharge of air, and a solenoid valve for sealing the supplied air in the brake when closed, and discharging the air from the brake when opened. The solenoid valve is supported by a solenoid valve support member mounted to the link frame such that the solenoid valve is positioned just near the brake. The rotating gantry can be more quickly braked and stopped while maintaining high irradiation accuracy.
