PROBLEM TO BE SOLVED: To provide a power transmission chain capable of reducing noise during driving and improving practical durability. SOLUTION: The chain 1 is equipped with a plurality of links 2 and a plurality of pairs of first and second pins 3 and 4 bendably connecting the links 2. The links 2 include a long pitch link 25 and a short pitch link 24. The first pin 3 includes a first specification member 31 and a second specification member 32. The transfer amount of a contact part T of the first specification member 31 accompanying bending between the corresponding links 2 is made larger than the transfer amount of the contact part T of the second specification member 32 accompanying bending between the corresponding links 2. The second specification member 32 is inserted into a rear through hole 10 of the long pitch link 25. COPYRIGHT: (C)2006,JPO&NCIPI
