    • PROBLEM TO BE SOLVED: To allow stable holding of a subject to be held while making use of an advantage of a motor that can displace finger parts largely.SOLUTION: Finger parts 12 and 13 bend and extend by using a joint part 15 as a fulcrum. A wire 21 is arranged along the finger parts 12 and 13 via the joint part 15. A motor 22 winds the wire 21 to stretch the finger parts 12 and 13 to a bending direction that corresponds to one side in a length direction and bend them. A high polymer actuator 25 that is arranged in the middle of the wire 21 and formed into a longitudinal shape by a high polymer material deforms elastically according to voltage application and extends/contracts in an axial direction by being restored to an original shape in response to suspension of voltage application. A lock mechanism A restricts relative movement of the wire 21 and the motor 22 after the wire 21 has been wound by the motor 22. The high polymer actuator 25 pulls the wire 21 to the bending direction by extending and contracting while the relative movement is restricted by the lock mechanism A.
    • 要解决的问题:通过利用能够大大移动指部的马达的优点,可以稳定地保持要保持的被摄体。解决方案:手指部件12和13通过使用接头部件15作为支点而弯曲和延伸 。 电线21经由接合部15沿着指部12,13配置。电动机22使电线21卷绕,使指部12,13沿与长度方向的一侧对应的弯曲方向拉伸。 配置在线材21的中间并由高分子材料形成为纵向形状的高聚合物致动器25根据电压施加而弹性地变形,并通过响应于原材料的形状而沿轴向延伸/收缩 暂停施加电压。 锁定机构A限制线21被电动机22卷绕后的线21和电动机22的相对运动。高聚合物致动器25通过延伸和收缩而将线21拉伸到弯曲方向,同时相对运动被限制 通过锁机构A.
