DAMPING VALVE

摘要

A damping valve includes an annular valve disc, the valve disc having an annular outer peripheral sheet that projects toward an axial direction of the valve disc, an inner peripheral sheet that is provided on an inside of the outer peripheral sheet and projects toward the axial direction, an annular window formed between the outer peripheral sheet and the inner peripheral sheet, and a port that communicates with the annular window. The damping valve comprises an annular leaf valve that is laminated on the valve disc and is seated/unseated on the outer peripheral sheet, an annular spacer that is interposed between the leaf valve and the inner peripheral sheet and sets an initial deflection amount of the leaf valve, and a positioning part that restricts positional deviation of the spacer in a radial direction relative to the valve disc.
