PROBLEM TO BE SOLVED: To eliminate a body which is unnecessary when the holding position of an optical cable is changed and to easily hold it at the hold position by providing a lead-in part with a fitting body which is fitted to the optical cable and a holder which has holding parts for holding the fitting body repeatedly detachably and is fitted to a box body. SOLUTION: A holding unit 52 is equipped with the fitting body 54 fitted to the optical cable which is led in from outside and the holder 56 which has the holding parts for holding the fitting body 54 so that it can be attached and detached repeatedly and is fitted to the back panel of the box body. Then when the holding position of the lead-in part of the optical cable is changed, the fitting body 54 fitted to the optical cable is detached from the holding parts of the holder 56 and mounted on another holding part of the fitting body 54. At this time, the fitting body 54 is repeatedly attachable to and detachable from the holding parts, so no unnecessary body is formed. Therefore, the cost for the position change is reducible. |
