Title: ROTATING MACHINE AND METHOD FOR PRODUCING ROTATING MACHINE
Abstract:
This rotating machine has a stopper (11) for blocking a through-hole (10) that passes through at least one element among a disc (3), a cover (4), and a blade, and is provided so as to connect to a space surrounded by the disc (3), cover (4) and blade. The stopper (11) is shaped in a manner such that the cross-section thereof that intersects the through direction in which the through-hole (10) penetrates gets gradually smaller toward the direction (direction of arrow B1) in which an external force acts on the disc (3), cover (4) and blade.
