CLAMP MECHANISM AND MANUFACTURING DEVICE FOR CATHODE- RAY TUBE

PROBLEM TO BE SOLVED: To provide clamping of a member to be clamped without displacing thereof, in regard to a clamp mechanism clamping a member to be clamped (for example, a color selecting mechanism of an aligner for manufacturing a fluorescent screen of a color cathode-ray tube). SOLUTION: In this clamp mechanism 40 holding a member to be clamped, a grip unit 42 for gripping the member to be clamped and a pressurizing unit 41 for applying a gripping force to the grip unit 42 are provided separately. It is comprised by spherically forming the contact part of the pressurizing unit 41 with the grip unit 42 and forming a grip part 54 of the grip unit 42, so that it makes a point contact with respect to the member to be clamped.
