    Abstract: A torque control device includes a seal structure sealing a clearance between a hollow object and a rotation shaft. The seal structure includes a particle seal, a liquid seal, an intermediate fluid which fills a middle chamber defined between the particle seal and the liquid seal, and a coating film having a hardness higher than that of magnetic particle. The coating film is arranged to at least at a seal perimeter part of the rotation shaft, and a seal gap is defined between the particle seal and the seal perimeter part.

    Abstract: A movable device includes an actuator element that deforms about an actuator axis in response to increase or decrease in energy of the actuator element. A driven body is coupled to the actuator element on the actuator axis and turned by deformation of the actuator element. A guide mechanism guides turning of the driven body about a turning axis coaxial with the actuator axis such that torsional deformation of the actuator element is directly transferred to the turning of the driven body.

    Abstract: An actuator device includes an actuator member, a drive subject, a drive device, and a tension applicator. The actuator member is configured to be deformed in response to application of energy to the actuator member from an outside of the actuator member. The drive subject is coupled to the actuator member. The drive device is configured to apply the energy to the actuator member and thereby displace the drive subject in a deforming direction of the actuator member. The tension applicator is configured to apply the actuator member a tension, which enables correction of a tension change generated by at least one of elongation and contraction of the actuator member that is induced by natural deformation of the actuator member.
