加熱構造。[Scope of Claim for Utility Model Registration] A lifting interlocking mechanism 19 is interposed between the lift arm 8 that protrudes from the hydraulic case 7 at the rear of the tractor A so as to be able to move vertically and the arm lifting/lowering lever for operating the lift arm. The lifting interlocking mechanism 19 is configured to move the lift arm 8 up and down in conjunction with the operation of the arm lifting operation lever, and the lifting interlocking mechanism 19 is provided with a damper device P. The damper device P acts as a damper on the lifting interlocking mechanism 19 only from a predetermined lowering position of the lift arm 8 which is rotating downward, thereby suppressing the downward rotation speed of the lift arm 8. A damper device heating structure for a lift arm lowering rotation speed control mechanism in a tractor, in which a damper device P is provided with a heater section 29 equipped with a thermostat.
