BALL CHAIN AND SHADE DEVICE
The present invention provides a ball chain that makes it possible to provide a fail-safe function to metal ball chains. Provided is a ball chain in which metal balls 16a are linked by a metal link shaft 16b, wherein a first end portion 17 and a second end portion 18 are coupled by a coupling part 21. The coupling part 21 comprises a first metal connector 22a provided with a first fitting protrusion 28a, a second metal connector 22b provided with a second fitting protrusion 28b, and a coupling member 23 for coupling the first metal connector 22a and the second metal connector 22b. A resin core member 31 of the coupling member 23 has a first fitting recess into which the first fitting protrusion 28a is fit and a second fitting recess 32b into which the second fitting protrusion 28b is fit. When a pulling force is applied that exceeds the pulling force during normal operation, at least the fitting protrusion 28a, 28b is dislodged from the fitting recess due to the elasticity of the resin in the resin core member 31.
本发明提供能够对金属制珠链设置故障安全功能的珠链；该珠链利用金属连杆轴(16b)连结金属滚珠(16a)，第一端部(17)和第二端部(18)通过连结部(21)被连结；连结部(21)具备：具有第一嵌合突部(28a)的第一金属连接器(22a)、具有第二嵌合突部(28b)的第二金属连接器(22b)、以及将第一金属连接器(22a)与第二金属连接器(22b)连结的连结部件(23)；连接部件(23)的树脂芯材(31)具备供第一嵌合突部(28a)嵌合的第一嵌合凹部和供第二嵌合突部(28b)嵌合的第二嵌合凹部(32b)；当被施加超过通常操作时的拉力的拉力时，由于树脂芯材(31)的树脂的弹性，至少嵌合突部(28a)、(28b)从嵌合凹部脱离。
