Claims

[Scope of utility model registration request]

A plurality of ladder elements are foldably and pivotally connected between their adjacent parts, and the uppermost ladder element is pivotally and pivotally connected to a fixed frame provided around the opening in the ceiling, and the fixed frame is connected to the fixed frame. In a folding ladder device that can be stored in the attic where a waist-folding link is pivotally connected between the upper ladder body and the upper ladder body to supplement the pivotal connection strength between the upper-tier ladder body and the fixed frame, the first part of the waist-folding link on the fixed frame side is A folding ladder device stored in a ceiling, which is provided with temporary fixing means between the link and the fixed frame, which elastically engages with the first link when the upper ladder body is in an extended position, and which releases with a release force exceeding a certain level. .
