ACTUATOR AND METHOD OF MANUFACTURING ACTUATOR

To achieve improvement in quality of a gelatinous damper member and efficiency of manufacturing an actuator in the actuator connecting a movable body and a support body by using the gelatinous damper member.SOLUTION: An actuator 1A includes a gelatinous damper member 9 connecting a support body 2 and a movable body 3, and a magnetic driving mechanism 6 for vibrating the movable body 3 relative to the support body 2. When assembling the support body 2 and the movable body 3, a method of manufacturing the actuator 1A includes: an assembling step for arranging a soluble mold member 4 at a position where the support body 2 and the movable body 3 face each other, and forming a hollow section 5 facing the support body 2 and the movable body 3; a charging step for charging a gel material 10 in the hollow section 5; a hardening step for hardening the gel material 10 charged in the hollow section 5; and a mold member removing step for injecting a solvent 19 to an outer side of the mold member 4, and discharging, to the outside, a solution obtained by solving the mold member 4 with the solvent 19 through a space between the support body 2 and the movable body 3.SELECTED DRAWING: Figure 5 【課題】ゲル状ダンパー部材を用いて可動体と支持体とを接続するアクチュエータにおいて、ゲル状ダンパー部材の品質向上およびアクチュエータの製造の効率化を図る。【解決手段】アクチュエータ１Ａは、支持体２と可動体３とを接続するゲル状ダンパー部材９と、可動体３を支持体２に対して振動させる磁気駆動機構６を備える。アクチュエータ１Ａの製造方法は、支持体２と可動体３とを組み立てる際、支持体２と可動体３とが対向する箇所に可溶性の型部材４を配置して、支持体２および可動体３に面する中空部５を形成する組立ステップと、中空部５にゲル材料１０を充填する充填ステップと、中空部５に充填されたゲル材料１０を硬化させる硬化ステップと、型部材４の外側に溶剤１９を注入し、溶剤１９で型部材４を溶かした溶液を支持体２と可動体３の間の空間から外部に排出する型部材除去ステップとを含む。【選択図】図５
