According to the present invention as set forth in claim 3, an introduction space for introducing the towing vehicle is provided below the upper table, and a connection member adapted to a connection recess provided in the towing vehicle is provided at an upper portion of the introduction space, and the introduction space is provided. When the towing vehicle is introduced into the space and the connecting member is inserted into the connecting concave portion and the connecting member is releasably retained and connected to the towing vehicle, a compact state is achieved at the time of connection and a narrow passage is provided. Can be used. According to the present invention as set forth in claim 4, the lock pin is movably supported and is biased in the lock state holding direction, and the connecting member is provided with a hooking portion hooked by the lock pin, and the connecting member is provided. The connecting member is provided with an interlocking locking mechanism for locking the locking part to be releasably locked by the connecting member moving in opposition to the urging force in association with the operation of inserting the locking pin in the coupling recess of the towing vehicle. As a result, the connection can be performed in a comfortable posture, and the use of a dedicated carriage and the station for connecting the carriage are not required. According to the present invention described in claim 4, since the interlocking locking mechanisms are symmetrically arranged, it is possible to easily connect the two carriages.
