Abstract

A metal gasket includes a coil spring (30a, 30b) that forms a ring, an inner cover (40a, 40b) that covers the coil spring (30a, 30b), and an outer cover (50) that covers the inner cover (40a, 40b). The inner cover (40a, 40b) has a hole (101a, 101b) for draining water from the metal gasket.
