Abstract: A valve includes: a leaf valve component; an opposing surface opposing to the component, the opposing surface being configured to prohibit passage of working fluid in a liquid path where the component is arranged; and a seating surface configured to come into contact with the component and prohibit passage of the working fluid in the liquid path in a case in which the component is elastically deformed by a predetermined amount, wherein, in an allowing stroke, during which the passage of the working fluid is allowed, the component is elastically deformed in a direction away from the seating surface so as to allow the passage of the working fluid, and the predetermined amount is set such that the component comes into contact with the seating surface when the speed of a piston exceeds an upper limit value of a predetermined normal range in a restricting stroke.

Abstract: A damping valve includes: a ring-shaped leaf valve having either one of an outer circumference and an inner circumference as a free end, the free end being allowed to be deflected toward both sides in the axial direction; a ring-shaped opposing portion that opposes the free end of the leaf valve with a gap; a first sub leaf valve stacked on one side of the leaf valve in the axial direction; and a first passage formed in the leaf valve so as to extend in parallel with the gap, the first passage being configured to be opened when the leaf valve is deflected in the direction away from the first sub leaf valve.
