Title: Actuator device and method for manufacturing the actuator device
Inventor: FUKADA MARI
IPC: H02N11/00
Filed: 2018-11-14
Abstract: To provide an actuator device which can avoid thermal resistance between a heating member and an operation member from increasing resulting from heating to the operation member.SOLUTION: Polymer fiber 12 deforms according to temperature change in the range in which contact stress which is generated between polymer fiber 12 and heating wire 14 remains in elastic limit of polymer fiber 12 or less. Thus, even if polymer fiber 12 deforms according to temperature change, it is possible to avoid plastic deformation of polymer fiber 12 resulting from the contact stress. Accordingly, when polymer fiber 12 was heated by heating wire 14 and then the heating is canceled, polymer fiber 12 returns to the original shape before heating by heating wire 14. Therefore, it is possible to avoid thermal resistance between heating wire 14 and polymer fiber 12 from increasing resulting from heating to polymer fiber 12.SELECTED DRAWING: Figure 1
