<p>PROBLEM TO BE SOLVED: To sandwich a roller so that a connecting inner link does not stand on the roller chain connection tool side, when connecting a roller chain.SOLUTION: A notch part 10 is formed by successively forming a taper 9 (a sequential taper 9a) approaching an opposed claw part 2 toward the tip end of a claw part 2 and a taper 9 (an inverse taper 9b) separating from the opposed claw part 2 toward the tip end of the claw part 2, in a back face part 8 being the outside in the sandwiching direction of the claw part 2. This claw part 2 is inserted between two rollers R1 and R2 of an inner link L1, and when sandwiching one roller R1 by this claw part 2, since a clearance is formed between the notch part 10 and the other roller R2, the inner link L1 can be prevented from standing by abutment between the back face part 8 and the other roller R2.</p> |
