PROBLEM TO BE SOLVED: To improve the durability and the reliability by connecting a yoke to a tension regulating cylinder using a tapered uneven part to suppress the movement of the yoke in the vertical direction. SOLUTION: This crawler tension regulating device 31 comprises an idler wheel 9, a yoke 32, a tension regulating cylinder 34, a compression spring 24, etc. A recessed part 33 is provided on a rear end side of the yoke 32, and a projection part 36 is provided on a forward rod 35 of the tension regulating cylinder 34. An outer circumferential surface of the projection part 36 is fitted to an inner circumferential surface of the recessed part 33 in an attachable/ detachable and close manner, and the yoke 32 is connected to the tension regulating cylinder 34 in a condition close to a single rigid body. The sliding and collision between the yoke 32 and the tension regulating cylinder 34 can be prevented, and the durability and reliability can be improved thereby.
