One embodiment of the present invention relates to a security structure for a retract apparatus which is configured such that an inlet hole of the retract apparatus is not arbitrarily opened. That is, the security structure for a retract apparatus arranges a security member before a coupling member, which is linked with a shutter. Thus, the shutter is opened and closed only when a confined state of the coupling member is released by using an interference member of a specific shape, which adequately manipulates the security member in a set direction. |
