PURPOSE: A power transmission chain is provided to reduce frictional loss and restrict loss of a connecting pin, thereby obtaining a stable running position and recurring abrasion of a chain guide. CONSTITUTION: A power transmission chain(100) comprises a pair of left and right inner link plates(110) with a bush hole in which both ends of a cylindrical bush(120) are pressed and inserted, a roller which is loosely inserted to the outside of the bush, a pair of left and right outer link plates(140) which are arranged on two outer sides of the inner link plates, and a connecting pin(150) which is inserted and freely rotated in the bush and fixed to a pin hole of the outer link plates by being pressed on both ends thereof to connect the inner and outer link plates in turn in the longitudinal direction of the chain so that the inner and outer link plates can slide along a chain guide. |
