Abstract
A chain joint for a power transmission chain comprises a joint pin and a projecting bush having brims swelling outwardly both its ends with at least one a slit extending longitudinally through the bush. The projecting bush is inserted into a pin hole and a bush hole of the chain, and the joint pin is pressed in an inner hole of the projecting bush. Then, the projecting bush is spread outwardly due to the slit and fits in the pin hole perfectly. Furthermore, the brims engage with the outer link plates on their outsides to prevent the projecting bush from coming off.
