Abstract: Disclosed is a vacuum double-tube spacer for a cryogenic liquid transfer line arranged between an inner tube in which cryogenic liquid flows and an outer tube which surrounds the inner tube from outside for maintaining the vacuum state between the inner and outer tubes. The spacer is formed of a plate on which multiple outer contact points coming in point-contact with the inner surface of the outer tube are arranged. Also, the spacer has multiple conical inner contact points protruding from the inner surface of a through-hole through which the inner tube penetrates, and coming in contact with the outer surface of the inner tube.
