PROBLEM TO BE SOLVED: To decrease variation in turning/tightening torque and to avoid the shortening of the life of a roller bearing owing to the generation of rust, etc. after a sterilization/disinfection process using ozone water, oxygenated water, peracetic acid, etc. under a corrosive environment for aseptic filling. SOLUTION: This cap mounting fixture 1 is provided with a fixture main body 3 mounted on the spindle 2 of a capping machine and moving with the spindle 2, a chuck part 4 holding a cap C, a magnetic clutch 8 for transmitting the rotation of the spindle 2 to or releasing the rotation from the chuck part 4, and a deep groove ball bearing 5 provided between the main body 3 and the check part 4 and supporting the chuck part 4 able to rotate relative to the main body 3. The inner ring 21, the outer ring 22 and the roller 23 of the ball bearing 5 are made of a nonmagnetic material. COPYRIGHT: (C)2006,JPO&NCIPI
