ソーバー。 A cylinder consisting of an outer shell and an inner shell, an axially magnetized magnet fixed to a base valve disposed at the bottom of the inner shell via a magnetic case made of a non-magnetic material, and a liquid inside the inner shell. It consists of a piston rod which is tightly and slidably fitted and has an orifice and a check valve at its end, and a magnetically sensitive element fixed to the end face of the piston rod facing the magnet, A shock absorber with a displacement detection function that can detect relative displacement between the piston rod and the cylinder even when the piston rod and the cylinder rotate relative to each other by directly detecting magnetic flux with a magnetic sensing element.
