A loop taker (18) has a loop taker body (20) molded of resin in one piece, and a hook (22) made of metal. A rotary shaft (13) is fitted in the center of the loop taker (18), and a set screw (17) threadedly inserted in the end of this rotary shaft holds down the loop taker (18). A pin (36) fixedly installed on the rotary shaft (13) is fitted in a radially extending groove (37) in the loop taker (18), whereby the loop taker (18) is connected to the rotary shaft (13) so that it will not rotate relative to the rotary shaft.
