PURPOSE:To provide the roller for detaching the connection component enabling to eliminate the damages of the component by abutting to the ring which is made by providing a recessed part on the back face of the rubber member provided for bringing into contact with the backing face the detached component of the roller to detach the connection part with feeding in order plural components which are connected in hoop shape. CONSTITUTION:The roller 21 for detaching connection components to equip with a cutting edge 11, pin 9 and flange 15 has the rubber ring being inserted into a groove 23. However the ring 22 that the outer peripheral face 24 comes into contact with an actuator 1 forms a semi-circular shaped recessed part 26 on plural places of the inner peripheral face 25. Therefore when the actuator 1 comes into contact with the backing face 7, the ring 22 is expanded in the thickness t direction on its contact part, also the semi-circular shaper of the recessed part 26 and the circular shape of the outer peripheral face 24 are crushed and deformed as shown in full line by the shape of prior to the contact shown in a dotted line. This deformation reverts to the original shaper by the restoring force of the ring 22 itself when the ring 22 is rotated and said contact is released. As the result the same result as the hardness of the rubber material used for the ring 22 being reduced <=30 deg. is obtd. and the damages of detached component can be prevented. |
