在に突設したリフトアーム８と、同リフトアーム
操作用のアーム昇降操作レバーとの間に昇降連動
機構１９を介設して、同昇降連動機構１９により
リフトレバー１４操作に連動したリフトアーム８
の上下回動作動がなされるように構成すると共に
、昇降連動機構１９中には、ダンパー装置２８を
設けて、同ダンパー装置２８が下降回動するリフ
トアーム８の所定下降位置からのみ同昇降連動機
構１９に緩衝機能して、同リフトアーム８の下降
回動速度を抑制するようにしてなるリフトアーム
下降回動速度制御機構において、昇降連動機構１
９に緩衝機能するダンパー装置２８をピストロツ
ド２８ｄのみ外部へ突出自在に収納ケース２８ａ
中に収納して、適宜ピストンロツド２８ｄの収納
ケース２８ａ内収納も可能としてなるトラクタに
おけるリフトアーム下降回動速度制御機構の解除
構造。 An elevating interlocking mechanism 19 is interposed between a lift arm 8 protruding from the hydraulic case 7 at the rear of the tractor A so as to be movable up and down, and an arm elevating operation lever for operating the lift arm. The lift arm 8 is linked to the lift lever 14 operation.
In addition, a damper device 28 is provided in the vertical movement interlocking mechanism 19, and the damper device 28 interlocks the vertical movement only from a predetermined lowering position of the lift arm 8 which rotates downward. In the lift arm lowering rotational speed control mechanism which functions as a buffer to the mechanism 19 and suppresses the lowering rotational speed of the lift arm 8, the lifting interlocking mechanism 1
9, a damper device 28 having a buffering function is stored in a storage case 28a such that only the piston rod 28d can freely protrude to the outside.
This is a release structure for a lift arm lowering rotation speed control mechanism in a tractor, which allows the piston rod 28d to be stored in the storage case 28a as appropriate.
