To provide a trailer coupling device that can be coupled to tractors having different coupling heights.SOLUTION: The coupling height of a king pin 22 is adjusted by selecting a sleeve 71, 72 (75, 76) at a lifter 41 side into which one pin is inserted and a sleeve 73, 74 (77, 78) at the lifter 41 side into which the other pin is inserted. Thus, a trailer can be coupled to tractors having different coupling heights.SELECTED DRAWING: Figure 2

    【課題】異なる連結高さのトラクタに連結させることが可能なトレーラの連結装置を提供する。【解決手段】一方のピンを挿入させる昇降部41側のスリーブ71,72(75,76)と、他方のピンを挿入させる昇降部41側のスリーブ73,74(77,78)とを選択することで、キングピン22の連結高さを調整する。これにより、トレーラを異なる連結高さのトラクタに連結することが可能となる。【選択図】図2
