Abrégé

A steering device includes a rack shaft, a pair of tie rods, a rack housing portion, a pinion gear provided on one end side of the rack housing portion, a first supporting portion configured to support the one end side of the rack housing portion, and a second supporting portion configured to support the other end side of the rack housing portion. The second supporting portion is movable in an axial direction of the rack housing portion from a proper position where the second supporting portion fixes the rack housing portion by being mounted on the vehicle body to an escaping position on the side of the pinion gear. The escaping position is a position where a distance from a tip of the tie rod on the other end side of the rack housing portion to the second supporting portion is equal to or longer than a length of twice the entire length of the tie rod.

Abrégé

Provided is a cylinder device comprising a piston rod inserted in a cylinder so as to be capable of moving forward and backward. The piston rod has: a rod section extending to the outside of the cylinder; and a piston connected to an end of the rod section and moving in a slidable manner within the cylinder. The rod section has: an in-rod space formed within the rod section and communicating with the piston-side chamber of the cylinder; a first communication passage for connecting the in-rod space and the rod-side chamber of the cylinder; and an orifice plug provided in a replaceable manner in the first communication passage. The piston is connected to the rod section so as to cover a part of the orifice plug.

A bellows (2) of a dust boot (1, 30) having large diameter parts (3) and small diameter parts (4) disposed alternately covers a piston rod (R) projecting from a cylinder (C). A bump stopper (B) fixed to the cylinder (C) projects into the bellows (2) as a projecting portion. The bellows (2) comprises a first section (M) which passes a projecting end of the projecting portion according to the elongation and contraction of the piston rod (R) and a second section (L) located therebelow. By making the small diameter parts in the second section (L) have a smaller inner diameter than the small diameter part located at a boundary between the first section (M) and the second section (L), the bellows (2) can be made slim without interfering with the bump stopper (B).
