Title:
CLAMP MECHANISM AND REWINDING SHAFT USING THIS CLAMP MECHANISM
Document Type and Number:
Japanese Patent JP3632175
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a clamp mechanism constituted by limited components which improves maintenance performance and reduces the working width and a rewinding shaft using this clamp mechanism.
SOLUTION: In this clamp mechanism 10 mainly constituted by a holder 20, bearings 30a and 30b and a lock member 40, the inside of the holder 20 is divided into two chambers to receive the pair of bearings 30a and 30b and the lock member 40 retractable in the radial direction. At this time, the bearings 30a and 30b are brought into contact with the lock member 40 at each of ends 33 and 43, and sliding motion of at least either of the bearings 30a and 30b is directly transmitted to retracting motion of the lock member 40. Moreover, a paper pipe B is attached to the clamp mechanism 10 to provide the rewinding shaft to rewind paper, film, etc.
