<p><P>PROBLEM TO BE SOLVED: To provide a detection mechanism capable of reliably recognizing a folding action of a lifting platform when the lifting platform is housed in a folded manner under a vehicle floor and having a simple configuration. <P>SOLUTION: The detection mechanism includes a body frame 10 slidable with respect to a vehicle, a hydraulic cylinder mechanism 15 for retracting the body frame under the vehicle floor, a lifting platform 60 that is foldable and has a top surface becoming flat-plate-shaped in an expanded state, a linkage mechanism for lifting which is provided on the body frame 10 side, and drives to lift the platform 60, and a detection mechanism that detects a folded state of the platform 60. The detection mechanism has a moving body 110 urged in a direction protruding from a roller 101 toward a folded platform portion, and a sensor 120 that detects a state where the moving body 110 has been pressed down by the folded platform portion. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
