PROBLEM TO BE SOLVED: To provide a door opening/closing device in which a limit switch mounted to a receiver is not damaged by impact when a door is closed in the door opening/closing device openably/closably mounted to an entrance side of a lifter load-carrying platform in a traveling lifter for placing a cargo on a load-carrying platform of a truck or the like. SOLUTION: The limit switch 18 and a slidable detection member 21 are provided on the receiver 14 engaged with a distal end of a front door when it is closed and an arm distal end roller 26 of the limit switch 18 is contacted with cam groove surfaces 21a, 21b formed on a side part of the detection member 21 with a step. Spring force making a distal end project from a receiving surface 23 is urged to the detection member 21 and the cam groove surfaces 21a, 21b are formed such that the arm distal end roller 26 is separated from a body 19 when the front door 11 is closed and the detection member 21 is retreated.
