Abstract: To bring a propulsion mechanism into reliable contact with a duct wall and transfer just a propulsion force to the duct wall without transferring an unnecessary retraction operation. An actuator for intraductal moving body includes: a propulsion mechanism (32, 36, 54, 56) which generates a drive force via a duct wall to generate a propulsion force for movement in a duct; a base mechanism (30, 34, 80) which supports the propulsion mechanism and causes the propulsion mechanism to abut against and separate from the duct wall; and two or more pairs of bilayer mechanisms provided axially symmetrically.
