Title:
アクチュエータ
Document Type and Number:
Japanese Patent JP6867252
Kind Code:
B2
Abstract:
To provide an actuator which has favorable electric resistance and which can prevent overheat fusion cutting.SOLUTION: In an actuator, a linear conductor is wound around a fibrous polymer material in a spiral manner with a predetermined gap, and the actuator drives by heating. A relation between the average Iof the pitch (I+D) of the spiral structure of the linear conductor and the standard deviation σ of the pitch (I+D) is expressed by σ/I×100≤10. It is preferable that the linear conductor is wound around the fibrous polymer material in a spiral manner and bonded and fixed.SELECTED DRAWING: Figure 1
