PROBLEM TO BE SOLVED: To provide a hydraulic cylinder for steering which can prevent generation of contact sound when a wheel is steered.SOLUTION: A hydraulic cylinder for steering 1 comprises a pair of cylinder guides 9 which are fitted to a cylinder tube 6 and movably guides both end side portions of a cylinder rod 8, and plural stud bolts 11 which connect the pair of cylinder guides 9 in cooperation with nuts 10. The stud bolt 11 has a rod part 21, and a screw part 22 which is positioned on an end side of the rod part 21 and is engaged with the nut 10. A diameter of the rod part 21 is larger than a diameter of the screw part 22. The cylinder guide 9 has an open hole 24 through which the screw part 22 penetrates, and a counter boring part 25 which is so provided as to be communicated with the open hole 24 and in which a boundary part of the rod part 21 with respect to the screw part 22 is accommodated.SELECTED DRAWING: Figure 5
