Abstract
A fiber cleaver is provided in which a circular blade can be efficiently used without increasing the workload imposed on the worker. The fiber cleaver includes a main body supporting a slider such that the slider is movable in the front-back direction. A disc-shaped circular blade configured to make a flaw in an optical fiber is rotatably provided to the slider. A columnar protrusion stands on a base of the main body. An engaging member engaging with a gear that rotates together with the circular blade is provided at the upper end of the columnar protrusion. The columnar protrusion is connected to an engaging member, which engages with the slider, with a spring interposed therebetween. The base has first to third recessed portions each anchoring the engaging member. The angle of rotation of the circular blade is changed among three angles with the position where the engaging member is anchored.
