PROBLEM TO BE SOLVED: To provide a cable feed-out device that can suppress torque loss and chain sagging to the minimum level and easily perform maintenance.SOLUTION: A cable feed-out device has: a fixed-side rotation shaft 4; a mobile-side rotation shaft 10 that is movable so as to approach to and separate from the fixed-side rotation shaft 4; driving means 8 for rotationally driving the fixed-side rotation shaft 4; and a transmission mechanism 14 for transmitting the rotation of the fixed-side rotation shaft 4 to the mobile-side rotation shaft 10. The transmission mechanism 14 has: a transmission gear 44 fixed to the mobile-side rotation shaft 10; an idle gear 46 engageable with the transmission gear 44; a first link member 56 for linking the mobile-side rotation shaft 10 and an intermediate rotation shaft 48; a first transmission sprocket 50 fixed to the intermediate rotation shaft 48; a second transmission sprocket 52 fixed to the fixed-side rotation shaft 4; a transmission chain 54 suspended between the first and second transmission sprockets 50, 52; and a second link member 58 for linking the intermediate rotation shaft 48 and the fixed-side rotation shaft 4. |
