PROBLEM TO BE SOLVED: To prevent vibration caused by rotation of a flexible shaft from being transmitted to a hand to handle a rotation transmitting shaft. SOLUTION: A flexible shaft liner assembly 12 is inserted in an outer tube 11, and a flexible shaft 13 is inserted in a flexible shaft liner 14. The flexible shaft liner 14 has two projecting parts 142 continuously extending in its longitudinal direction and two projecting parts 141, 143 having notches at plural places on the longitudinal direction. A rubber vibration isolator 15 is engaged with the notches, and the two projecting parts 142 are fitted in a groove formed on the inner surface of the rubber vibration isolator 15. The flexible shaft liner 14 is internally fitted in the outer tube 11 by the outer surface of the rubber vibration isolator 15 abutting on the outer tube 11. |
