PROBLEM TO BE SOLVED: To solve the problem that a beryllium copper alloy, which is used since sparks fly in metallic fixtures in the case of collision, is not more extended than iron, not deformed even when a impact load is imposed by falling, and is used as it is after fall since a connection belt hardly has a fall trace at a glance though one fall gives a little twist in some cases, so as to break a ring after several times of falling and not to perform holding. SOLUTION: One side of the connection belt 6 is connected to the ring 5 which is arranged in the intersection part of a back part shoulder belt 1 and the other side is arranged in a breast part, so as to mount the connection belt 6. A fall display part is arranged in the connection belt 6 and the several times of usage is prevented. Specifically, the middle part of the connection belt 6 is folded to have a superimposition part 63. A tension member 7 is disposed along the superimposition part 63. In the case of falling, the tension member 7 is cut so as to open the superimposition part 63. Thus, falling is confirmed in the display part 8. COPYRIGHT: (C)2006,JPO&NCIPI
