Abstract
An air cylinder is actuated to remove a winding reel from a winding shaft. When a piston rod is driven to advance in an axial direction of the winding shaft toward a transmission rod and abuts and presses against a pressure-applied end portion of the transmission rod against a first coil spring, the piston rod receives reactive force from the pressure-applied end portion. On receiving reactive force, the air cylinder moves back in an axial direction of the winding shaft, which is opposite to that in which the piston rod advances, on a linear guide against a second coil spring and a pawl piece abuts against and engages with a flange. After the pawl piece and the flange have engaged with each other, the air cylinder is prevented from moving back in the axial direction still further. Pressing force of the piston rod onto the pressure-applied end portion of the transmission rod when a diameter of a collet sleeve is reduced acts on the pawl piece via the flange and then does not act on a bearing as thrust load.
