Claims

[Claims for Utility Model Registration] 1. A receiving member 9 for receiving and supporting the crawler tension ring 2 is slidably and removably attached to the truck frame 1, and the receiving member 9 of the truck frame 1 is used as a reaction force point to Crawler tension ring 2
The tension spring 12, which slides and biases the crawler towards the tension side of the crawler, is attached to the truck frame 1 together with the receiving member 9 in a state where it can be freely attached to and removed from the said receiving member 9, and in a state where it is in contact with the receiving portion 13. Part 9
A tension wheel attachment structure of a crawler traveling device provided between a spring receiving member 11 slidably attached to a spring receiving member 11 and the receiving member 9, one end of which is in contact with the receiving member 9, and , the other end side contacts the spring receiving member 11, and the receiving portion 9 receives the crawler tension ring 2 via the receiving member 9 as a reaction force member via the spring receiving member 11. Attaching a tension wheel to a crawler traveling device in which a spacer 15 or 16 for supporting and suppressing compressive elastic deformation of the tension spring 12 is removably formed between the receiving member 9 and the spring receiving member 11. Departmental structure. 2. A receiving member 9 for receiving and supporting the crawler tensioning wheel 2 is slidably and removably attached to the truck frame 1, and the receiving member 9 of the crawler tensioning wheel 2 is attached using the receiving portion 13 of the truck frame 1 as a reaction force point.
The tension spring 12, which slides and biases the crawler towards the tension side of the crawler, is attached to the truck frame 1 together with the receiving member 9 in a state where it can be freely attached to and removed from the said receiving member 9, and in a state where it is in contact with the receiving portion 13. Part 9
A tension wheel attachment structure of a crawler traveling device provided between a spring receiving member 11 slidably attached to a spring receiving member 11 and the receiving member 9, one end of which is in contact with the receiving member 9, and , the other end side is in contact with the receiving portion 13 to receive and support the crawler tension ring 2 via the receiving member 9 with the receiving portion 13 as a reaction force member, and the tension spring 1
A spacer 17 or 18 for suppressing compressive elastic deformation of the receiving member 9 and the receiving portion 13
A structure for attaching a tension wheel of a crawler traveling device, which is detachably formed between the parts.
