A bracket is provided, the pulley support member being inserted into the inner side of the endless rotation belt, and fixing the pulley support member to the transport case in a position straddling the endless rotation belt; A bracket located along one side of the endless rotating belt fixes the pulley support member to the transport case, and releases the fixation to allow the endless rotating belt to be replaced. The structure is configured to be switchable between a state in which a space is formed, and this structure provides the following effects.

[Effect]

When replacing the endless rotating belt, by switching the bracket located along one side of the endless rotating belt, the fixation between the pulley support member and the conveyance case by the bracket is released. The endless rotating belt can be attached to and detached from the guide pulley through the space formed between the conveyance case and the pulley support member, and after the endless rotating belt has been replaced, the bracket can be moved by switching the bracket. The pulley support member can be fixed to the transport case.

Moreover, among the brackets that fix the pulley support member to the conveyance case, the bracket located along one side of the endless rotating belt is switched, and the endless rotating belt is replaced.
When replacing the belt, a bracket located along the other side of the endless rotating belt holds the pulley support member and the conveyance case in a connected state.

〔Effect of the invention〕

Therefore, when replacing the endless rotating belt, it is necessary to remove one shaft end of each of the plurality of guide pulleys from the bearing part,
There is no need to remove the guide pulley along with its bearing from the conveyance case, and the work of replacing the endless rotating belt can be done more easily and quickly than in the past.

Furthermore, since the pulley support member is connected to the transport case even when replacing the belt, the pulley support member can be fixed to the transport case without having to reposition the pulley support member after replacing the endless rotating belt. The above effects can also be further enhanced.
