Above-mentioned supporter 262 is embedded in above-mentioned lug boss 226a outside installing hole 262a place, utilize set bolt 265 to be fixed on the gripper shoe 264 that links to each other with this lug boss 226a.This supporter 262 has three backing rolls 266, and these backing rolls 266 snap in the circular mounting hole 261a of above-mentioned auxiliary rotary body 261 and the decentralized configuration perimembranous at supporter 262.Auxiliary rotary body 261 props up on above-mentioned supporter 262 by above-mentioned three roller 266 pivots, around the axle center Z of the central part that is configured in above-mentioned supporter 262 from above-mentioned reel axis of rotation X1 prejudicially rotation.But the end one of the reel frame side of above-mentioned each connecting rod 263 is connected on the rotation fulcrum 242a of corresponding above-mentioned tooth support portion 242 with rotating freely.The end on the auxiliary rotation side of above-mentioned each connecting rod 263 can be connected in the top of auxiliary rotary body 261 with rotating freely.
Thus, tooth maintaining body 260, rotation along with rotating drum 227, auxiliary rotary body 261 is utilized from rotating drum 227 to be rotated around the axle center Z different with reel axis of rotation X1 via the driving force that connecting rod 263 transmits, and utilize each tooth support portion 242 of connecting rod 263 rotary manipulations rotation fulcrum 242a and with respect to each tooth support portion 242 of reel frame 241 rotary manipulations, no matter the rotation of rotating drum 227 how, all can be operable to, keep the distolateral tooth 246 of each tooth support portion 242 and the posture that inner tines 245 is extended from tooth support portion 242 downwards.
Figure 33 has the end view that the second tooth configuration portion that implements the rotating drum 227 of structure locates.
Have second rotating drum 227 of implementing structure and have distolateral tooth 246 and inner tines 245, the 242 development length L1 that extend are set at shorter than the development length L2 of inner tines 245 242 extensions from the tooth support portion from the tooth support portion with distolateral tooth 246.
That is to say, if rotating drum 227 is with distolateral tooth 246 ground connection, because distolateral tooth 246 has the bending strength greater than inner tines 245, so easy deformation or breakage.But, even take place under the situation of ground connection at rotating drum 227, also be inner tines 245 ground connection and distolateral tooth 246 is earth-free, strain takes place because of having less bending strength in inner tines 245 easily, plastic deformation or breakage do not take place because of earth-free in distolateral tooth 246, thereby inner tines 245 and distolateral tooth 246 all are difficult to take place plastic deformation or breakage.
As substituting of the inner tines 245 of the foregoing description, also can adopt following structure to implement, that is, inner tines 245 is configured as the case of bending of band corner angle, thus make the end side of inner tines 245 than the end side of distolateral tooth 246 more by the outer circumferential side of rotating drum.At this moment, also can reach purpose of the present invention.
