After that, each screw rod 12 threadedly engaged with the rope cleat 32 is turned to bring each screw rod 12 into contact with the block member 13.
  • each screw rod 12 is further turned, and the terminal portion 5b of each rope 5 is drawn into each socket 3.
  • the block member 13 is divided and detached from the rope 5, and each screw rod 12 is detached from the rope cleat 32.
  • the rope cleat 32 which collectively grasps a plurality of ropes 5 separate from each other, constitutes the rope grasping member, so there is no need to separately prepare a rope grasping member solely for the purpose of drawing the ropes 5 into the sockets 3, thereby achieving a further reduction in the number of components.
  • the block member 13 has a plurality of division members 22 and 23, it is also possible to form the block member integrally without dividing it. This helps to reduce the number of components forming the block member 13, thereby achieving a reduction in cost. In this case, after the rope 5 is grasped by the rope grasping member, it is impossible to pass the rope 5 through the block member through-hole 14, so the rope 5 is passed through the block member through-hole 14 before being grasped by the rope grasping member.
  • the block member 13 is detached from the rope 5 after the rope 5 is drawn into the socket 3
  • the block member 13 it is possible for the block member 13 to be detached from the rope 5 or left in contact with the forward end portion of the socket 3 after the rope 5 is drawn into the socket 3.
  • the screw rods 12 are in contact with the block member 13, and the socket 3 receives the screw rods 12 displaced with respect to the rope grasping member through the intermediation of the block member 13, it is also possible for the screw rods 12 to be brought into direct contact with the forward end portion of the socket 3 if there is provided at the forward end of the socket 3 a space allowing the screw rods 12 to be brought into contact therewith. This makes it possible to eliminate the block member 13, thus achieving a further reduction in the number of components. Further, this helps to further facilitate the operation of drawing the rope 5 into the socket 3.
  • the socket 3 connected to the rope 5 is a wedge type socket in which the terminal portion 5b of the rope 5 is engaged between the inner surface of the rope passing hole 6 and the wedge 7, it is also possible to adopt a babbit type socket into which the terminal portion of a rope formed by turning up each strand is drawn.
  • the rope is disentangled into a plurality of strands after being passed through the socket, and each strand is turned up to form the terminal portion.
  • the rope grasping member is attached to the portion of the rope drawn out of the socket.
