The lift arm 8 is configured to move up and down in response to the operation of the lift lever 14, and an air damper 28 is provided in the up/down interlocking mechanism 19, and the air damper 28 rotates the lift arm downward. A downward rotational speed control mechanism for a lift arm in a tractor, which acts as a buffer for the lifting interlocking mechanism 19 only from a predetermined lowering position of the lift arm 8 to suppress the downward rotational speed of the lift arm 8.
