PROBLEM TO BE SOLVED: To provide a resin chain reducing shock and vibration apt to generate in meshing with sprockets in rotational driving of the chain, ensuring a stable silent chain driving state, and reducing abrasion elongation as a chain. SOLUTION: W-shaped meshing teeth 111 meshing with teeth of the sprocket and a ring plate 110 having a pair of pin holes 112 are joined with a pair of joint pins 120 and a locker pin 130, the joint pins 120 are fit and fixed to a plate 140 for rotatably supporting pins adjacently arranged on the outermost side of the ring plate 110 to form the resin chain, and a pin rolling mechanism in which a circular arc outer circumferential surface 130a of the locker pin 130 and a circular outer circumferential surface 120a of the joint pin 120 face and slidably contact within the pin hole is constituted in the resin chain.
