Abstract
An actuator including a fixing member, a movable member, and a hollow hole, wherein a wire body passes through the hollow hole. The wire body includes at least a pair of first wire bodies having a first diameter and a pair of second wire bodies having a second diameter smaller than the first diameter. Each of the pair of first wire bodies is a single wire or a twisted pair wire. The pair of second wire bodies are twisted pair wires.
Claims12
An actuator, comprising:
- a fixed member,
- a movable member which rotates relative to the fixed member,
- a hollow hole which penetrates the actuator,
- a filamentary body which passes through an interior of the hollow hole,
- a first affixation part for affixing one portion of the filamentary body, and
- a second affixation part for affixing another portion of the filamentary body, wherein
- the filamentary body includes at least a pair of first filamentary bodies having a first diameter and a pair of second filamentary bodies having a second diameter which is smaller than the first diameter,
- each of the pair of first filamentary bodies is a single wire, and
- the pair of second filamentary bodies is a twisted pair of wires.
