PROBLEM TO BE SOLVED: To provide a crawler stretching adjustment device capable of correcting stretching of the crawler to desired stretching when stretching of the crawler is increased/decreased and detecting increase/decrease of stretching of the crawler. SOLUTION: A driven wheel 3 is supported on a pair of idler forks 5 and respective base ends 5a of the idler fork 5 is fixed to a support plate 6. A spring 8 and a slide body 11 are stored in an idler bracket 44 fixed to the support plate 6 and the spring 8 is guided by guide rods 9, 10. The slide body 11 is pressed to the support plate 6 side in resistant to spring force of the spring 8 by a piston rod 13, a distal end 28 of the guide rod 10b is projected from a through hole 6a formed on the support plate 6 in response to the compression state of the spring 8 and spring force accumulated in the spring 8 can be detected.
