The invention provides a pull-out brake which prevents a pull-out detection part from deformation and allows an on spring having stored energy to automatically release even though the brake main body is directly placed on the ground while being pulled out. The pull-out brake is provided with the brake main body (100), a pull-out frame (200) receiving the brake main body (100), a pull-out mechanism (15) pulling out the brake main body from the pull-out frame (200), the on spring (17) storing the energy for powering on the switch contact of the brake main body (100), a position detection guide rail (202) arranged on the inner side of the side surface of the brake main body or the inner side of the upper surface, and a guide rail detection lever (51) arranged on the brake main body (100) to detect the position detection guide rail (202) and to release the on spring (17) if the lever is corresponding to the detection state of the position detection guide rail (202). |
