As explained above, according to the present invention, a straight pin 6 without any processing is used, and the cam part 8 formed protruding from the lifting pawl 7 is used to prevent the pin 6 from coming off.
Since the lid 10 is integrally formed with the cam part 8, the lifting claw 7 can be attached very easily and inexpensively, and the pin 6 can be prevented from coming out by simply pressing the above 10 from above. Since the locking protrusions 13, 15 can easily fit into the locking recesses 8', 16 with just one step, no other parts are required for the operation, and there is no possibility of inconveniences such as loss of parts. Since the lid 10 is configured to form a part of the cam portion 8, the lid 10 can be moved easily and quickly as no tools are required. As mentioned above, it not only acts to prevent the pin 6 from coming off, but also becomes substantially flush with the cam surface 8a and top surface 8b of the cam portion 8, and as a result, the raising and lowering action of the lifting pawl 7 based on the cam portion 8 is smooth. It is possible to reduce the accumulation of dust, etc. on the portion of the lid 10 that comes into sliding contact with the guide surface 9 and the cases 11 and 12, and in addition, the cases 11 and 12 can be placed in sliding contact with or close to the lid 10. As a result, the pin can be more securely prevented from coming off, and the lifting chain 1 can be prevented from moving blindly.
