PURPOSE:To prevent missing of a collar by disposing a spring collar between opposed U-shaped metal fittings and engaging a pin and a collar at the disassembly time. CONSTITUTION:To disassemble a coupling, one end of a stick member is made in contact with one face of the pin 2 and the other end of the stick member is impacted or hardly pressed. A spring collar 5 is then compressed and deformed automatically, on account of which a pin 7 with the spring collar can be taken off easily. The spring collar 5 is so engaged as not to be removed from the pin 2 after the disassembly so that a fear that the spring come off or miss can be get rid of. |
