PURPOSE:To more smoothly switch a movable side optical fiber even though the number of acting times becomes large. CONSTITUTION:A driving piece 13 is formed of a leaf spring material having comparatively high hardness such as stainless so as to have forked parts 13a and 13a on a top, part, and is attached to an armature 11. A connecting member 7 is formed of a metallic material such as aluminum alloy which is comparatively light and whose hardness is low in a cylindrical bar-like shape in order to easily move, and two round pins 14 and 14 formed of the same material as the material of the driving piece 13, that is, the material having the same hardness, are erectly set on one end of the member 7 in a state where they are aligned in a longitudinal direction and they pass through on both sides. And in the driving piece 13, the forked parts 13a and 13a are inserted in a gap between the two round pins 14 and 14, then the movable side optical fiber 5 fixed on the movable body 6 integrally moving with the connecting member 7 is switched so that its optical axis may align with either of the pair of the fixed side optical fibers 1 and 2 by driving the connecting member 7 in an axial direction through the two round pins (member to be driven) 14 and 14. |
