To achieve, with a simple structure, movement and coming-off prevention of a coupling pin.SOLUTION: A conveyance dolly coupling device 10 includes: a dolly coupling frame 21 attached to a towing vehicle 11; an operation mechanism 51 provided on a dolly coupling frame 21 so as to be operable; and a coupling pin 36. The connection pin 36 is provided in the dolly coupling frame 21 and is moved, by an operation of the operation mechanism 51, between a coupling position where the coupling pin is inserted into a to-be-coupled portion 16 to couple the conveyance dolly 15 to the towing vehicle 11 and a coupling release position where the coupling pin is pulled out of the to-be-coupled portion 16 to release the coupling. At least one of the dolly coupling frame 21, the operation mechanism 51, and the coupling pin 36 has a coming-off prevention structure that holds the coupling pin 36 at the coupling position when the conveyance dolly 15 is coupled to the towing vehicle 11 and regulates movement of the coupling pin 36 from the coupling position to the coupling release position.SELECTED DRAWING: Figure 1

    【課題】連結ピンの移動及び抜け止めを簡単な構造で実現する。【解決手段】搬送台車連結装置10は、牽引車両11に取付けられる台車連結フレーム21と、台車連結フレーム21に操作可能に設けられた操作機構51と、連結ピン36とを備える。連結ピン36は、台車連結フレーム21に設けられ、かつ操作機構51の操作により、被連結部16に挿入されて搬送台車15を牽引車両11に連結する連結位置と、被連結部16から抜け出して上記連結を解除する連結解除位置との間で移動させられる。台車連結フレーム21、操作機構51及び連結ピン36の少なくとも1つは、搬送台車15の牽引車両11に対する連結時に連結ピン36を連結位置に保持して、連結ピン36が連結位置から連結解除位置へ移動するのを規制する抜け止め構造を有している。【選択図】図1
