To provide a connecting device or the like that can easily release connection between two connection objects to improve the convenience.SOLUTION: A connecting device 1 of a towing vehicle 2 includes a connecting pin 13, a locking arm 22, and an actuator 23. The connecting pin 13 is provided to be rotatable between a connection position where the connecting pin is fitted with a connecting plate 3a of a truck 3 to connect the towing vehicle 2 to the truck 3, and a connection release position where the connecting pin is released from the fitting with the connecting plate 3a so that connection between the towing vehicle 2 and the truck 3 is released. The locking arm 22 is driven by the actuator 23 between a locking position where the locking arm locks the connecting pin 13 so that the connecting pin becomes unrotatable from the connection position toward the connection release position side, and a locking release position where the locking arm releases the locking of the connecting pin in the connection position.SELECTED DRAWING: Figure 12
【課題】2つの連結対象間の連結を容易に解除することができ、利便性を向上させることができる連結装置などを提供する。【解決手段】牽引車2の連結装置1は、連結ピン13、ロックアーム22及びアクチュエータ23を備える。連結ピン13は、台車3の連結板3aと嵌合し、牽引車2と台車3を連結する連結位置と、連結板3aとの嵌合が外れることにより牽引車2と台車3の連結が解除される連結解除位置との間で回動自在に設けられており、ロックアーム22は、アクチュエータ23により、連結ピン13を連結位置から連結解除位置側に回動不能になるように係止するロック位置と、連結位置への係止を解除する係止解除位置との間で駆動される。【選択図】図12
