WIRE CABLE TENSION MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a small sized tension mechanism for wire cable. SOLUTION: This wire cable tension mechanism is comprised of wire cable 4 connecting a drive part 1 and a moving member 3, and a tension case 5 provided with a straight slide groove 6 passing through a middle part of the wire cable 4. A slide member 7 is slidably stored in the slide groove 6. A base end of cable cover 8 of the wire cable 4 extending toward the drive part 1 or the moving member 3 is connected to an end part of the slide member 7. A tip of the cable cover 8 is fixed on a fixing part 10 at a fixed relative position to the tension case 5. A coil spring 12 having a centerline in parallel with the slide groove 6 is provided between the slide groove 6 and the slide member 7.
