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.
