Claims

[Scope of utility model registration request]

A laying reel used when laying optical fiber coated with a metal tube, in which a rotating handle is attached to the rotating shaft of a winding drum rotatably supported by a support via a torque limiter. A reel for laying metal tube-coated optical fiber, characterized in that when a winding torque exceeding a set load is applied to the rotating shaft, no driving force is transmitted from the rotating handle.
