Abstract
A folding structure of a carrier includes an expansion member connected between a base frame and an extension member. As the expansion member pivotally passes through the point of over-tangency (the turning point of balance of force), the extension member is extended or folded due to a liner bias force provided by the expansion member and also due to the change in length of the expansion member. For example, the expansion member starts to elongate itself when passing through the point of over-tangency, generating a force to extend the extension member in an extended position automatically.
