Claims (1)
空気の供給によって膨張可能なチューブを配置するとと
もに、前記チューブの内部に、前記チューブの収縮時に
おけるたるみを防ぐための軸を設置してなり、又前記軸
本体の周壁に設けられた溝内に摺動自在に挿着片を配置
し、前記チューブの膨張時にチューブの外周によって押
動されて前記挿着片の先端が、前記軸本体の外周に挿嵌
された巻心の内面に押し着けられるように前記挿着片の
内面を前記チューブの外周に相対するように設置してな
り、更に前記挿着片の内面外縁に、前記溝の内周縁に係
合して前記挿着片の溝からの抜出しを防止するための張
出部を設けてなる巻心用駆動軸。・ Inside the hollow shaft body that is driven to rotate,
A tube that can be expanded by supplying air is disposed, and a shaft is installed inside the tube to prevent the tube from sagging when it contracts, and a shaft is installed in a groove provided in the peripheral wall of the shaft body. An insertion piece is arranged to be slidable, and when the tube expands, it is pushed by the outer periphery of the tube so that the tip of the insertion piece is pressed against the inner surface of the core inserted into the outer periphery of the shaft body. The inner surface of the insertion piece is installed so as to face the outer periphery of the tube, and the inner surface of the insertion piece is further engaged with the inner peripheral edge of the groove so as to extend from the groove of the insertion piece. A drive shaft for the winding core, which is provided with an overhang to prevent the core from being pulled out.
