The present invention relates to a technique for preventing tenter malfunctioning that is attributable to a tenter clip misoperation which results from a chain assembly being affected by vibration during tenter driving or factors such as high temperature and heat during dyeing, processing and drying. The tenter clip-mounted chain assembly according to the present invention includes: a roller unit fixing a fastening unit at both ends between upper and lower supporting portions, the fastening unit being bored and having a roller coupled outside; and a connection where a fastening member having a threaded portion at an end is provided to protrude from both ends so that the roller unit can be fastened via the fastening unit and in a pivotal manner. A bush with a gap is inserted into the fastening unit, and the bush is formed of an alloy of one or more selected from W, Mg, Al, Cu, Ti, Ag, Ni, Si, Cr, Mn, Mo, Zn, Zr, Fe, Ca, Li, and Be. |
