Summary:PROBLEM TO BE SOLVED: To enable a smooth operation along an axial direction while suppressing a rotation motion of a displacement block, in a fluid pressure cylinder.SOLUTION: A fluid pressure cylinder 10 has a displacement part 20 displaceable to the other end part side of a body 12. A connection body 70 connected to a piston rod 26 of a cylinder part 16 is inserted in a block body 92 of the displacement part 20 via a spring 108, and a suction rod 18 is connected substantially parallel with the connection body 70 and a buffer rod 112 connected to the connection body 70. Also, an outer peripheral surface 116a of a rod part 116 in the buffer rod 112 and an inner peripheral surface 110a of a bush 110 provided on the outer peripheral side of the rod part 116 are formed in a tapered shape in which diameters are reducing gradually toward the body 12 side respectively. Then, in a state where the displacement to the lower side of the block body 92 is restricted, when a further load is imparted, the buffer rod 112 is displaced relatively with respect to the block body 92 against a resilient force of the spring 108, and a gap between the buffer rod 112 and the bush 110 in the radial direction increases. 【課題】流体圧シリンダにおいて、変位ブロックの回転動作を抑制しつつ、軸方向に沿って円滑に作動させる。【解決手段】流体圧シリンダ１０は、ボディ１２の他端部側に変位自在な変位部２０を有し、該変位部２０のブロック体９２にシリンダ部１６のピストンロッド２６に連結された連結体７０がスプリング１０８を介して挿入されると共に、前記連結体７０及び該連結体７０に連結されたバッファーロッド１１２と略平行にサクションロッド１８が連結される。また、バッファーロッド１１２におけるロッド部１１６の外周面１１６ａと、該ロッド部１１６の外周側に設けられたブッシュ１１０の内周面１１０ａは、それぞれボディ１２側に向かって徐々に縮径するテーパ状に形成される。そして、ブロック体９２の下方への変位が規制された状態で、さらなる荷重が付与された際、スプリング１０８の弾発力に抗してバッファーロッド１１２が前記ブロック体９２に対して相対変位し、前記バッファーロッド１１２とブッシュ１１０との間の径方向における間隙が大きくなる。【選択図】図１
