The semi-trailer 1 includes: a king pin 20 connectable to a fifth wheel coupler included in the semi-tractor or a fifth wheel coupler 45A included in the dolly 40; a wedge 30 disposed behind the king pin 20 and insertable between a pair of guides 49 included in the dolly 40; and an actuator configured to drive the wedge 30. The actuator moves the wedge 30 to an operation position and a storage position. The wedge 30 is moved to the storage position when the semi-trailer 1 is connected to the semi-tractor, and is moved to the operation position when the semi-trailer 1 is connected to the dolly 40.SELECTED DRAWING: Figure 3 【課題】トラクタやドリーとの干渉を回避可能なウェッジを有するセミトレーラを実現する。【解決手段】セミトレーラ1は、セミトラクタ及びドリー40の両方に連結可能である。セミトレーラ1は、セミトラクタが備える第5輪カプラ又はドリー40が備える第5輪カプラ45Aに連結されるキングピン20と、キングピン20の後方に設けられ、ドリー40が備える一対のガイド49の間に挿入されるウェッジ30と、ウェッジ30を駆動するアクチュエータと、を有する。前記アクチュエータは、ウェッジ30を作動位置と収納位置とに移動させる。ウェッジ30は、セミトレーラ1がセミトラクタに連結されるときには前記収納位置に移動され、セミトレーラ1がドリー40に連結されるときには前記作動位置に移動される。【選択図】図3
