Claims

[Scope of utility model registration request]

In parent-child pantographs of the spring rising air lowering type, in which a child pantograph with a small action stroke is mounted on the top of the pantograph frame that collects current from the overhead contact line, the child pantograph has a folding lever that moves in conjunction with the lower frame, and the child pantograph has a folding lever that moves in conjunction with the lower frame. The parent pantograph carrying the pantograph has a lowering device for lowering the pantograph and a cradle for receiving the folding lever of the child pantograph, and both the parent pantograph and the child pantograph can be folded simply by operating the parent pantograph's lowering device. A folding device for vehicle pantographs.
