Abstract: A valve includes a valve disc and annular-plate shaped leaf valves. The leaf valves are laminated on each of the one chamber side and the other chamber side of the valve disc. The valve disc includes annular bosses and seats. The boss is formed at each of the one chamber side and the other chamber side to support the leaf valves. The seats are formed on outer peripheral sides of the respective bosses on the one chamber side and the other chamber side. The leaf valves are left from/seated on the seats. At least one of the seats on the one chamber side and the other chamber side are disposed to project with respect to the bosses. An outer peripheral end on the seat on the other chamber side is disposed on an outer peripheral side with respect to an outer peripheral end of the leaf valve.
