(Effect of the Invention) According to the present invention, the locking bodies having a plurality of bolts are attached to the left and right abutments that support the conveyor chains at both ends in the width direction of the endless traveling body via the chain guide bodies. In addition, a guide support portion and a guide locking portion are formed on the locking body, and a guide having a communication long groove for inserting the guide supporting portion and a lower surface for inserting the guide locking portion is formed on the chain guide body. Since the long groove is formed and the locking projections that are locked to the guide locking portion are formed on both sides of the communication long groove,
By inserting the chain guide body into the lock body using this lock body as a guide, the chain guide bodies can be easily attached to the left and right abutments with one touch, and the bolts can be tightened. By doing so, the locking projecting edges on both sides of the chain guide body can be reliably sandwiched between the guide locking portion of the locking body and the abutment, and therefore, the endless rolling on the left and right abutments is achieved. The chain guide body for guiding the conveyor chain at both ends in the width direction of the body can be efficiently and easily locked securely.

Also, by loosening the tightening of each bolt, it is possible to easily release the pinching of the locking projecting edges on both sides of the chain guide body, so each bolt is locked while still attached to the abutment. The chain guide body can be easily removed from the abutment using the body as a guide. Therefore, the chain guide body can be easily attached to and detached from the abutment base.

Further, the left and right chain guide bodies are connected to the guide long groove by sandwiching the locking projecting edges on both sides of the communication long groove by the guide locking portion of the locking body and the abutment, thereby rotating the conveyor chain at both ends. It is possible to reliably prevent the supporting portions of the left and right chain guide bodies that guide and support the movement of the upper part of the row from floating due to temperature changes.

In addition, stoppers for the outer ends of the upper traveling parts of the conveyor chain are formed at the end edges of the supporting surface on the conveyor frame side that supports the upper traveling parts of the conveyor chains formed on the upper parts of the left and right chain guides. The position of the conveyor chain of the endless traveling body can be reliably regulated from the left and right parts by the left and right stoppers, and the upper traveling portion of the endless traveling body vibrates vertically during traveling and moves horizontally. Can be reliably prevented from coming off the guide ridge,
Therefore, the endless traveling body can be stably rotated while being guided by the guide ridges by the conveyor chain and the chain guide body at both ends.

Further, since the left and right chain guide bodies are respectively formed with oil reservoirs by the support surfaces on the left and right conveyor frame sides and the stoppers protruding from the end edges of the support surfaces, the oil reservoirs of the left and right chain guide bodies are formed. The lubricating oil that falls from the conveyor chain at both ends of the endless traveling body is securely received and stored at this section, and this lubricating oil flows out from between the conveyor frame and the abutment and is contaminated with the lubricating oil. Can be prevented.

Therefore, the mounting work and the replacement work of the chain guide body can be carried out extremely efficiently, and the chain guide body guides and supports the endless rolling body and does not move in the traveling direction. You can always go around with good stability.
