PROBLEM TO BE SOLVED: To prevent a winding shaft from being unwound by a method wherein tongues are formed at the right and the left bearing plates whereon bearings for rotatively bearing the winding shaft are provided, and while small protuberances are provided at the outside of the front end parts of the tongues, a disk is provided at one end of the winding shaft and a holding part is provided at the other end, and a number of recessed parts are formed at equal intervals at the periphery of the disk. SOLUTION: For a tube squeezing device 1 used for squeezing a tube filled with sealant, toothpaste or the like, holes 8 and 9 are bored at its right and left bearing plates 2 and 3 and a winding shaft 11 is inserted through the holes 8 and 9. A slit 12 is formed at the winding shaft 11 and protuberances 13... are formed in projection at the inner wall of the slit 12, and the tube inserted therein is certainly supported therewith at its bottom. A disk 16 is fixed at the tail end side of the winding shaft 11 and recessed parts 17... are provided in cutting at equal intervals at the periphery of the disk 16. Tongues 21 are formed with U-shaped notches provided at the outside of the bearing plates 2 and 3 and a small protuberance 23 in a hemispherical shape is formed in projection at the outside of each of the tongues for making the recessed part 17 engaged therein. |
