Abstract: A mold used for centrifugal casting includes a mold body formed in a cylindrical shape and a lid member (40) that is detachably assembled to an end part of the mold body in an axial direction. The lid member includes a lid body (41) that is attached to an opening part formed at the end part of the mold body, a protrusion part (450) that is fitted to the mold body, and a spring that applies elastic force to the lid body in a direction in which the lid body closely contacts the mold body.
