PROBLEM TO BE SOLVED: To provide a thermal soil disinfector that can automatically attain a self-correction to a straight travelling figure in no need of an artificial operation, when the disinfector moves obliquely. SOLUTION: A pipe 35 for feeding hot water is mounted on the running frame 31 in a trailed type form and equipped with the hot water injector 36 in a rake shape for injecting hot water into the soil. In the meantime, a pair of left and right plate members 54, 54 which dig into the soil of the farm fields and a traction arm are pivotally are swingably and pivotally set to the travelling frame 31 around the vertical axis line. Further, the couple of plate members 54, 54 are connected in the toe-out posture, and the plate couple 54, 54 and the traction arm 56 are connected through the synchronizing mechanism that swings them in the same direction.
